Mitochondrial disease v0.1075 MT-TW Zornitza Stark Phenotypes for gene: MT-TW were changed from Encephalomyopathy to Mitochondrial disease (MONDO:0044970), MT-TW-related
Mitochondrial disease v0.1074 MT-TW Zornitza Stark Publications for gene: MT-TW were set to
Mitochondrial disease v0.1073 MT-TW Zornitza Stark edited their review of gene: MT-TW: Added comment: DEFINITIVE by ClinGen.

At least 10 individuals reported. Age of onset in affected individuals ranged from childhood to adulthood. Clinical features in affected individuals included LSS, microcephaly, developmental delay and regression, cognitive decline, fatigue, seizures, ataxia, chorea, muscle wasting, axonal neuropathy, diabetes, liver steatosis and fibrosis, constipation, recurrent vomiting, failure to thrive, pigmentary retinopathy, ptosis, optic atrophy, ophthalmoplegia, sensorineural hearing loss, and hypertrophic and dilated cardiomyopathy. Brain imaging was variable and ranged from normal to findings consistent with LSS to generalized atrophy and white matter involvement.

Muscle biopsies showed ragged red fibers, COX-deficient fibers, and decreased respiratory chain enzyme activities. Metabolic laboratory investigations revealed elevated blood and cerebrospinal fluid lactate. Heteroplasmy levels in affected individuals were highest in muscle and/or liver when multiple tissues were assessed (25 - >95 % in muscle, 1 to >95% in blood, >95% in liver, 1-92% in skin fibroblasts, and 5% in urine when assessed). Functional studies to support variant pathogenicity.; Changed publications: 7695240, 9266739, 9673981, 12776230, 15054399, 18337306, 19809478, 26524491, 23841600, 30937556; Changed phenotypes: Mitochondrial disease (MONDO:0044970), MT-TW-related
