Genes affected

DNAJC1 (HGNC:20090): (DnaJ heat shock protein family (Hsp40) member C1) The membrane protein encoded by this gene is a DNAJ-like heat shock protein that binds the molecular chaperone BiP. In addition, the encoded protein contains two SANT domains that have been shown to bind serpin alpha1-antichymotrypsin and inter-alpha trypsin inhibitor heavy chain 4. [provided by RefSeq, Jul 2016]

The c.986A>C (p.E329A) alteration is located in exon 9 (coding exon 9) of the DNAJC1 gene. This alteration results from a A to C substitution at nucleotide position 986, causing the glutamic acid (E) at amino acid position 329 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
