Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3

The NM_024591.5(CHMP6):c.133C>T(p.Arg45Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000581 in 1,583,604 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R45H) has been classified as Uncertain significance.

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.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.133C>T (p.R45C) alteration is located in exon 2 (coding exon 2) of the CHMP6 gene. This alteration results from a C to T substitution at nucleotide position 133, causing the arginine (R) at amino acid position 45 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
