A rare genetic intellectual disability syndrome with characteristics of macrocephaly, hypotonia, dysmorphic facial features (wide forehead, ptosis, downslanting palpebral fissures, enlarged and calcified external ears, large jaw), sparse body hair and tall stature. Hearing loss, insulin-resistant diabetes, and progressive distal muscle wasting (leading to joint contractures) have also been reported in adulthood. Rare manifestations include hypothyroidism, cerebral calcification, ataxia and peripheral neuropathy. There is evidence this disease is caused by heterozygous mutation in the ZBTB20 gene on chromosome 3q13.
