Lauren Rogers changed review comment from: 3 unrelated families with five affected children with homozygous or compound heterozygous loss of function missense and PTC variants. HEK293T cells show the missense variants are expressed at normal levels but exhibit reduced assembly with other BORC subunits and reduced ability to drive lysosome distribution. The BORCS8 PTC frameshift variant is expressed at lower levels and is completely incapable of assembling with other BORC subunits and promoting lysosome distribution. Zebrafish KO of the orthologous brocs8 causes decreased brain and eye size, neuromuscular anomalies and impaired locomotion, recapitulating some of the key traits of the human disease. Sources: Literature; to: 3 unrelated families with five affected children with homozygous or compound heterozygous loss of function missense and PTC variants. 5/5 hypotonia, failure to thrive, global developmental delay, profound intellectual disability, muscle weakness and atrophy, dysmorphic features. 3/5 with microcephaly, 3/5 with seizures, 4/5 with spasticity, 3/5 with scoliosis, 4/4 with optic atrophy.
