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.181A>G (p.K61E) alteration is located in exon 3 (coding exon 3) of the CHMP6 gene. This alteration results from a A to G substitution at nucleotide position 181, causing the lysine (K) at amino acid position 61 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
