We report on a child with a unique constellation of congenital anomalies suggesting a new syndrome. These consist of developmental delay; craniofacial abnormalities, including bilateral cataracts, ptosis, median nasal groove, malformed ears with associated neurosensory hearing loss; dental anomalies consisting of anomalous cusp morphology with unusual pointed extensions and delayed tooth eruption; short stature with marked delay in epiphyseal ossification; coronal clefts involving vertebrae T11-S2; and dislocated hips. A literature search and use of a computer-assisted syndrome-identification program failed to uncover an identical case.

We describe a 14-year-old boy with congenital bilateral cataracts, blepharophimosis, ptosis, choanal atresia, sensorineural hearing loss, short, webbed neck, poor esophageal motility, severe growth and mental retardation, skeletal anomalies, seizures, and no speech. As an infant, he had transient hypogammaglobulinemia requiring IVIG therapy. Cytogenetic studies show an apparently de novo visible duplication at 1p36.3. Fluorescence in situ hybridization (FISH) studies confirm that the common region for the 1p36 deletion syndrome (p58) is duplicated. Probes for D1Z2 at 1p36.3 and the subtelomeric region of 1p (TEL1p) are also duplicated. Array comparative genomic hybridization (aCGH) studies were done at three separate laboratories, each with somewhat different results. BAC whole genome array CGH suggests a single clone gain at the 1p terminus and a single clone deletion at 1p36.3. A targeted BAC array panel with higher resolution at the distal 1p36 region detects a telomeric duplication and an interstitial deletion. Oligonucleotide whole genomic aCGH shows the highest resolution and a more complex rearrangement: two duplications, an interstitial deletion, and a normal region. The MMP23A/B "matrix metalloproteinase 23A/B" genes are within the distal duplication region in our patient, and this patient does not have craniosynostosis. This is the first association of congenital cataracts, choanal atresia, and transient immune abnormalities with 1p36 duplication/deletion. This case illustrates the limitations of different cytogenetic technologies, and shows how three separate aCGH platforms allow for refined delineation and interpretation of the complex cytogenetic rearrangement which would not have been discovered by standard high-resolution chromosome analysis.

Dynamin 2 (DNM2)-related dominant centronuclear myopathy is usually a mild disorder, but more severe variants have been associated with mutations affecting the pleckstrin homology (PH) domain of the protein, mainly implicated in different forms of Charcot-Marie-Tooth Disease (CMT). Whilst DNM2-related CMT may feature non-neurological findings including cataracts, this has not been reported in DNM2-related centronuclear myopathy. We report a girl presenting from birth with hypotonia, respiratory and feeding difficulties. Motor development was delayed and at 9years she lost the ability to walk. She had ptosis, external ophthalmoplegia and bilateral cataracts. Muscle biopsy showed increase in central nuclei with type 1 hypotrophy and fibrosis. DNM2 screening revealed a novel heterozygous substitution (c.1862T>C; p.Leu621Pro) affecting the PH domain of the protein. Her further course was progressive and at 14years she died from respiratory failure. Our findings expand the phenotypical spectrum associated with DNM2 mutations and provide a new clinical indicator for involvement of this gene in patients with centronuclear myopathy.

Non-syndromic, multi-organ mitochondrial disorders (MIDs) are frequently missed if treating physicians are not aware of them. We report a 85 years old Caucasian male, referred for tonic-clonic seizures, presenting with a plethora of abnormalities, including neurodermitis, atopic dermatitis, diabetes, hypertension, renal insufficiency, non-specific colitis, urine bladder lithiasis, bilateral cataracts, atrial fibrillation, diverticulosis, polyneuropathy, vitamin-D-deficiency, renal cysts, left anterior hemi-block, right bundle branch block, pulmonary artery hypertension, and heart failure. Neurological investigations revealed ptosis, quadriparesis, fasciculations, dysarthria, dysdiadochokinesia, tremor, hyperkinesia, ataxia, leukoencephalopathy, and basal ganglia calcification. Based upon this combination of abnormalities a non-syndromic mitochondrial multi-organ disorder syndrome (MIMODS, encephalo-myo-cardiomyopathy) was diagnosed.
