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.

Nov 23, 2024

The c.452A>T (p.E151V) alteration is located in exon 6 (coding exon 6) of the CHMP6 gene. This alteration results from a A to T substitution at nucleotide position 452, causing the glutamic acid (E) at amino acid position 151 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
