Genes affected

DNAJC5 (HGNC:16235): (DnaJ heat shock protein family (Hsp40) member C5) This gene is a member of the J protein family. J proteins function in many cellular processes by regulating the ATPase activity of 70 kDa heat shock proteins. The encoded protein plays a role in membrane trafficking and protein folding, and has been shown to have anti-neurodegenerative properties. The encoded protein is known to play a role in cystic fibrosis and Huntington's disease. A pseudogene of this gene is located on the short arm of chromosome 8. [provided by RefSeq, Nov 2010]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.43).
• BP6: Variant 20-63895290-C-G is Benign according to our data. Variant chr20-63895290-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 384761.Status of the report is criteria_provided_single_submitter, 1 stars.
