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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.1255G>T (p.G419W) alteration is located in exon 11 (coding exon 11) of the DNAJC1 gene. This alteration results from a G to T substitution at nucleotide position 1255, causing the glycine (G) at amino acid position 419 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
