Genetic Variant DNAJC28:p.Asp352Gly (chr21-33488339-T-C) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001040192.3(DNAJC28):c.1055A>G(p.Asp352Gly) variant causes a missense change. The variant allele was found at a frequency of 0.000000698 in 1,432,710 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign 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. D352V) 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]
