Genes affected

CHMP6 (HGNC:25675): (charged multivesicular body protein 6) This gene encodes a member of the chromatin-modifying protein/charged multivesicular body protein family. Proteins in this family are part of the ESCRT-III (endosomal sorting complex required for transport III) which degrades surface receptors, and in biosynthesis of endosomes.

The c.400G>A (p.V134M) alteration is located in exon 5 (coding exon 5) of the CHMP6 gene. This alteration results from a G to A substitution at nucleotide position 400, causing the valine (V) at amino acid position 134 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
