Neurological examinations were made of 67 children and adults with congenital iodine-deficiency disorder (endemic cretinism) in four rural villages in highland Ecuador. There was a distinct and readily identifiable pattern of neurological deficits. These included, to varying degrees: deaf-mutism or lesser degrees of bilateral hearing-loss or dysarthria; spasticity, particularly involving the proximal lower extremities;
mental deficiency
of a characteristic type; and rigidity and
bradykinesia
. Not all of these elements were found in all cases. Less common features were strabismus, kyphoscoliosis and frontal-lobe signs. There were exceptional cases with hypotonia. In contrast, cerebellar function was largely spared, as were functions of emotion and attention, vegetative and autonomic functions, social interaction, and probably memory, except in the most severely involved.

Pontocerebellar hypoplasia type 6 (PCH6) is an autosomal recessive mitochondrial disease, typically characterized by pontine atrophy, vermian hypoplasia, infantile encephalopathy, generalized hypotonia, and intractable seizures. The purpose of this study is to describe the seizures and other neurological manifestations of
RARS
2 gene mutations and to compare the clinical features with other causes of progressive myoclonic epilepsy. Detailed history, physical examination, and clinical and genetic work-up were performed in 2 siblings who presented with progressive myoclonic epilepsy. One sibling, a 20-year-old woman, and the other a 24-year-old man, had a homozygous missense variant (c.848T>A; p.Leu283Gln) in exon 10 of the
RARS
2 gene. The female patient had action and audiogenic myoclonic jerks, postural tremors, spastic dysarthria, and
bradykinesia
, and her male sibling had similar features with oculomotor apraxia. The
RARS
2 gene mutation can present with myoclonic epilepsy,
mental retardation
, and pyramidal and extrapyramidal features, and is an important differential for causes of progressive myoclonic epilepsy.
