Green List (high evidence)

Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). There is sufficient evidence to promote this gene to Green at the next GSM panel update.

Panel Version: 1.128
At least 13 individuals from 8 unrelated families (PMIDs: 32808683; 33764426; 33851776) with biallelic variants in VPS41 (7 different variants reported). All affected individuals developed cognitive impairment (GDD/ID) and dystonia, and most also had hypotonia, ataxia, and cerebellar atrophy/hypoplasia. Supported by functional data showing that variants lead to lysosomal dysfunction.

Panel Version: 1.100
Single individual reported with homozygous canonical splice site variant resulting in exon 7 skipping, and global developmental delay and generalized dystonia. He attained a few words and voluntary limb movements but never sat unsupported. He had pale optic discs and an axonal neuropathy. From 6 years of age, his condition began to deteriorate, with reduced motor abilities and alertness. An MRI of the brain showed atrophy of the superior cerebellar vermis and slimming of the posterior limb of the corpus callosum. VPS41 is component of the HOPS complex and other genes in the complex have been implicated in movement disorders.
