ZMIZ1, zinc finger MIZ-domain containing 1, has recently been described in association with syndromic intellectual disability in which the primary phenotypic features include intellectual disability/developmental delay, seizures, hearing loss, behavioral issues, failure to thrive, and various congenital malformations. Most reported cases have been found to result from de novo mutations except for one set of three siblings in which parental testing could not be performed. With informed consent from the family, we report on a father and his two sons demonstrating autosomal dominant inheritance of a novel pathogenic ZMIZ1 variant, c.1310delC (p.Pro437ArgfsX84), causing this recently described neurodevelopmental syndrome. While they all show syndromic findings along with short stature and intellectual disability, only one child had sensorineural hearing loss. Moreover, severity of intellectual disability and eyelid ptosis were variable among the affected members. Our report demonstrates that phenotypic features of ZMIZ1-related neurodevelopmental syndrome are variable even within the same family and that parental testing to identify a mildly affected parent is needed.

Leigh syndrome (or subacute necrotizing encephalomyelopathy) is a rare neurodegenerative disorder characterized by psychomotor retardation or regression, typically occurring in stepwise decrements. Onset is typically between ages 3 and 12 months. Neurological manifestations include hypotonia, spasticity, movement disorders (including chorea), cerebellar ataxia, and peripheral neuropathy, whereas extraneurological manifestations may include hypertrophic cardiomyopathy, hypertrichosis, anemia, renal tubulopathy, liver involvement, ptosis, and muscle weakness. Approximately 50% of affected individuals die by age 3 years, most often as a result of respiratory or cardiac failure. We report a case of 22-month-old female child presenting to us with severe failure to thrive, dysmorphic features, hirsutism, external ophthalmoplegia epilepsy, and neuroregression with characteristic findings of Leigh's syndrome on neuroimaging and her muscle biopsy revealed evidence of mitochondrial respiratory chain defect involving complex IV and SURF1 mutation.
