Variant summary

Our verdict is Benign. Variant got -13 ACMG points: 1P and 14B. PP3BP4_ModerateBP6_Very_StrongBS2

The NM_006308.3(HSPB3):c.347G>A(p.Arg116Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000206 in 1,614,102 control chromosomes in the GnomAD database, including 3 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R116P) has been classified as Likely benign.

Genes affected

HSPB3 (HGNC:5248): (heat shock protein family B (small) member 3) This gene encodes a muscle-specific small heat shock protein. A mutation in this gene is the cause of autosomal dominant distal hereditary motor neuropathy type 2C.[provided by RefSeq, Sep 2010]
