Genes affected

DNAJC12 (HGNC:28908): (DnaJ heat shock protein family (Hsp40) member C12) This gene encodes a member of a subclass of the HSP40/DnaJ protein family. Members of this family of proteins are associated with complex assembly, protein folding, and export. Two transcript variants encoding distinct isoforms have been identified for this gene.

The c.542G>C (p.W181S) alteration is located in exon 5 (coding exon 5) of the DNAJC12 gene. This alteration results from a G to C substitution at nucleotide position 542, causing the tryptophan (W) at amino acid position 181 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
