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.

Ambry Genetics

Dec 21, 2023

The c.389C>T (p.T130M) alteration is located in exon 5 (coding exon 5) of the CHMP6 gene. This alteration results from a C to T substitution at nucleotide position 389, causing the threonine (T) at amino acid position 130 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
