dbSNP rs201623013: DNAJC28:p.Arg134Leu (chr21-33488993-C-A) – ACMG Classification: Uncertain_significance (4 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_001040192.3(DNAJC28):c.401G>T(p.Arg134Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,096 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R134Q) has been classified as Uncertain significance.

Genes affected

DNAJC28 (HGNC:1297): (DnaJ heat shock protein family (Hsp40) member C28) This gene encodes a member of the DnaJ heat shock protein family. The encoded protein, which contains a conserved N-terminal DnaJ domain, is thought to play a role in protein folding or act as a molecular chaperone protein. [provided by RefSeq, Oct 2016]
