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.158G>A (p.R53Q) alteration is located in exon 2 (coding exon 2) of the CHMP6 gene. This alteration results from a G to A substitution at nucleotide position 158, causing the arginine (R) at amino acid position 53 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
