Added comment: Four patients from two unrelated consanguineous families reported with homozygous variants (missense and stop-loss). Siblings from family 1 were diagnosed prenatally with diffuse subcutaneous oedema, cardiomegaly, corpus callosum agenesis, ventriculomegaly and hypoplasia of the cerebellum. Siblings from family 2 had slightly different presentations, which included anoxo-ischemic encephalopathy, isolated dyspnea, neonatal respiratory distress, neonatal jaundice, hypotonia, visual impairment, microcephaly; both siblings had severe delayed psychomotor development. Immunoblot analysis of protein expression in lysates from patient-derived fibroblasts demonstrated reduced MPC1 and MPC2 protein levels.

Mitochondrial disease v0.622 SLC25A46 Zornitza Stark changed review comment from: Hereditary motor and sensory neuropathy type VIB is an autosomal recessive complex progressive neurologic disorder characterized mainly by early-onset optic atrophy resulting in progressive visual loss and peripheral axonal sensorimotor neuropathy with highly variable age at onset and severity. Affected individuals also have cerebellar or pontocerebellar atrophy on brain imaging, and they show abnormal movements, such as ataxia, dysmetria, and myoclonus.

At least 10 unrelated families reported, supportive functional data.

Mitochondrial carrier protein.; to: Hereditary motor and sensory neuropathy type VIB is an autosomal recessive complex progressive neurologic disorder characterized mainly by early-onset optic atrophy resulting in progressive visual loss and peripheral axonal sensorimotor neuropathy with highly variable age at onset and severity. Affected individuals also have cerebellar or pontocerebellar atrophy on brain imaging, and they show abnormal movements, such as ataxia, dysmetria, and myoclonus. New PCH disease entity added by OMIM in 2021 to reflect the more severe end of the spectrum.

At least 10 unrelated families reported, supportive functional data.
