A family is described in which five males have late-onset facial weakness, dysarthria, dysphagia, and slowly progressive proximal weakness. Electrodiagnostic studies and muscle biopsy were compatible with spinal muscular atrophy. This family appears quite similar to several previously reported families with late-onset X-linked recessive spinal and bulbar muscular atrophy. Because of the relative homogeneity of this particular phenotype of spinal muscular atrophy, a single metabolic derangement was sought. Three obligate carriers were studied, and no abnormality was detected. A further family with this condition is briefly discussed.

A new syndrome of autosomal recessive spastic ataxia has been isolated in the Charlevoix-Saguenay region of Quebec. This syndrome is remarkably homogeneous and includes: spasticity, dysarthria, distal muscle wasting, foot deformities, truncal ataxia, absence of sensory evoked potentials in the lower limbs, retinal striation reminiscent of early Leber's atrophy and the frequent presence (57%) of a prolapse of the mitral valve. Biochemically, many cases show impaired pyruvate oxidation, others have hyperbilirubinaemia and some have low serum beta-lipoproteins and HDL apoproteins. These features are similar to those found in typical Friedreich's ataxia.

A study of chronic proximal spinal muscular atrophy was undertaken with the main aim of obtaining empirical recurrence risks for genetic counselling. Thirty-eight patients and their families were studied. Of these, 33 had similar clinical features and onset of disease in infancy or childhood. A division of these 33 patients by onset before or after 2 years (which was equivalent to whether or not they ever walked normally) gave recurrence risks for sibs which were higher with early onset. Among the sibs of patients with onset before 2 years, the incidence of disease was 1 in 5, due to most patients having an autosomal recessive disorder. A few patients, however, were thought to represent new dominant mutations. Among the families of index patients with onset after 2 years, the incidence of disease in sibs was only 1 in 15, but among their children it as 1 in 8. Both autosomal recessive and autosomal dominant forms therefore occurred in this age group, but it was concluded that nearly half the patients with onset after 2 had non-genetic motor neuron disease. The autosomal recessive form of chronic spinal muscular atrophy generally had onset before 2 years, but occasionally after 2. About a third of the patients never walked, and about half were in wheelchairs by age 10. No genetic heterogeneity within this form was demonstrated. Three remaining patients had distinctive clinical features associated with their proximal weakness, external ophthalmoplegia in one, dysarthria in another, and joint contractures in a third. Only 2 patients had onset in adult life, one of a probable recessive disorder and the other a probable dominant disorder.

The Troyer syndrome was found by Cross & McKusick (1967) in 20 members of 12 Old Order Amish families in Holmes County, Ohio; it is a form of hereditary spastic paraplegia combined with distal muscle wasting, i.e. signs of involvement of lower motor neurons. The condition usually begins at 1 to 2 years and progresses at variable rates. Further manifestations include growth retardation, delayed speech development with dysarthria and drooling, and cerebellar signs; mental functions are usually not affected but severe emotional lability is a common finding. Brothers in a Wisconsin Old Order Amish family are reported with spastic diplegia, mental retardation, behavioral disorder and shortness of stature; the condition apparently is not progressive, and may be a "new" syndrome but could also represent a variant of the Troyer syndrome. Autosomal recessive inheritance is most likely, although consanguinity of the parents could not be proven. Another child in this family suffers from focal scleroderma (morphea) which is not related to the neurological syndrome.

We restudied a family with X-linked mental retardation (XLMR) originally reported in abstract form by Davis et al. [1981]. All 8 living affected males were examined. Characteristics included severe mental retardation, spastic paraplegia, dysarthria, muscle wasting, scoliosis, broad shallow pectus excavatum, long face, large ears with minor modeling anomalies, foot deformities, joint contractures, and neck drop. Stature, OFC, testicular volume, high resolution chromosome and fragile X studies, and plasma amino acids were all normal. Their manifestations closely resemble those of a large family with XLMR originally reported by Allan et al. [1944] and restudied by Stevenson et al. [1990]. This condition has been termed the Allan-Herndon-Dudley syndrome (AHDS). As AHDS has been mapped to Xq21, mapping studies were undertaken to determine if this family maps to the same location. These studies demonstrate tight linkage to Xq21, with a maximum lod score of 2.88 obtained with probe pX65H7 (DXS72). Multipoint analysis located the mutant gene quite close to pX65H7 (multipoint Z = 4.14), slightly more proximal in Xq21 than was suggested by the data from the original AHDS family. It appears likely that this family is the second reported family with AHDS.

A 68-year-old man without familial history developed ataxic gait and sensory disturbance in the lower extremities. At the age of 74, neurological examination revealed marked cerebellar ataxia of all limbs, dysarthria, sensory disturbance of glove and stocking type in the extremities, and slight neurogenic muscular atrophy. There were no mental deterioration and dysautonomia. He died of pneumonia at the age of 74. Neuropathological findings. The cerebellum was decreased in size. Microscopically, there were severe disappearance of Purkinje cells in the cerebellar vermis and hemispheres. The molecular layer, granular cell layer, and cerebellar white matter were preserved. Neurons of the inferior olivary nuclei were also spared. In the spinal cord, there was myelin pallor in the posterior column predominant in Goll's fascicule and moderate atrophy of neurons in the anterior horn. Degeneration of the posterior roots was greater than that of the anterior roots. No abnormal findings were found in the extrapyramidal system, cranial nerves, and cerebrum. We compared this case clinicopathologically with other diseases with cortical cerebellar atrophy; alcoholic cerebellar degeneration, phenytoin intoxication, neuroleptic malignant syndrome, and subacute paraneoplastic cerebellar degeneration. In conclusion, idiopathic late cerebellar cortical atrophy (LCCA) was different clinicopathologically from the other diseases. Especially, LCCA showed the characteristic topography of Purkinje cells loss sparing the molecular and granule cell layers.

A case of rigid spine syndrome associated with rimmed vacuoles in muscle biopsy is reported. A 36-year-old man was admitted to our hospital because of gait disturbance and limited mortality of the spine. His family was free from any neuromuscular disorders. He was born in normal pregnancy and delivery. His physical development was normal. At age 7, he was unable to run fast. At age 36, he had right hemiparesis and dysarthria. He was diagnosed as cerebral infarction of the left basal ganglia by brain CT. Neurological examination revealed moderate proximal dominant muscular atrophy and weakness. His spine was straight, showing loss of physiological cervical and lumbar lordosis. The neck flexion was limited but the extension was full. And he had contracture of bilateral ankle joint. Laboratory findings were all normal. The electrocardiogram showed negative T wave in V4, V5 and QT interval elongation. The echocardiogram showed diffuse decrease of ventricular wall motion. Respiratory function test revealed decrease of vital capacity. Arterial blood gases on room air showed that the PaO2 and PaCO2 were 70 mmHg and 49 mmHg, respectively. The findings of electromyogram were compatible with myopathic change. Biopsy specimen of the biceps brachii muscle showed marked variation in fiber size, type 1 fiber predominancy and atrophy, and type 2B fiber deficiency. Numerous rimmed vaculoes were found in the same muscle. Four cases of the rigid spine syndrome with rimmed vacuoles have been described. Among them, three patients died in young ages and two suffered from constrictive respiratory failure. In rigid spine syndrome with rimmed vacuole formation, the cardiac and respiratory problems must be taken account intensively.

We report the case of a 62-year old man presenting with generalized muscular weakness, amyotrophy, dysarthria and dysphagia. Neurological examination showed bilateral pyramidal signs and lingual fasciculations. The clinical diagnosis was amyotrophic lateral sclerosis, since only shivers and weight loss pointed to hyperthyroidism. However, after several months the patient developed typical manifestations of hyperthyroidism. After treatment of hyperthyroidism, the neurological symptoms disappeared. Although this association is extremely rare, one must have in mind the possibility of thyroid dysfunction when studying patients with amyotrophic lateral sclerosis.

The patient, a 31-year-old married woman, noticed spasticity on walking at the age of 19 accompanied by ataxia, dysarthria and dysphagia. Facial twitching and dystonic movement of extremities have been observed since age 27. A sister of her father showed the similar ataxia and dysarthria, and expired of pneumonia at the age of 45. On admission at the age of 29, neurological examinations revealed nystagmus, marked spasticity with pathological reflexes and clonus, cerebellar ataxia, dysarthria and dysphagia, diffuse muscle wasting, fasciculation in facial musculature, and generalized slow dystonic movement. By neuro-otological studies bilateral MLF syndrome with upward gaze limitation and decreased velocity of saccadic eye movement were detected. Surface EMG at rest showed a dystonic discharges on the extremities. Needle EMG disclosed a systemic neurogenic change with reduced interference and high amplitude potentials. Atrophy of the brainstem was remarkable on the cranial CT and MRI. These abnormal eye movements, especially bilateral MLF syndrome and generalized dystonia seem to be quite unusual in the variety of spinocerebellar degenerations. On reviewing detected clinical descriptions on Joseph disease this case can be probably included.

A 32 year old male is described with an onset of upper limb postural tremor in adolescence followed by muscle cramps. Progressive proximal amyotrophy and weakness in the limbs developed late in the third decade. Examination disclosed, in addition, bilateral facial weakness and mild dysarthria. Enzyme studies revealed hexosaminidase A and B deficiency, indicating a diagnosis of Sandhoff disease. Intra-axonal membranocytoplasmic bodies were present in a rectal biopsy. The presentation, which resembled that of X-linked bulbospinal neuronopathy, widens the clinical spectrum for disorders related to G(M2) gangliosidosis.
