Genes affected

DNAJC10 (HGNC:24637): (DnaJ heat shock protein family (Hsp40) member C10) This gene encodes an endoplasmic reticulum co-chaperone which is part of the endoplasmic reticulum-associated degradation complex involved in recognizing and degrading misfolded proteins. The encoded protein reduces incorrect disulfide bonds in misfolded glycoproteins. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

The c.271G>T (p.D91Y) alteration is located in exon 4 (coding exon 2) of the DNAJC10 gene. This alteration results from a G to T substitution at nucleotide position 271, causing the aspartic acid (D) at amino acid position 91 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
