Genes affected

HSPA4 (HGNC:5237): (heat shock protein family A (Hsp70) member 4) Predicted to enable ATP binding activity. Involved in chaperone-mediated protein complex assembly and protein insertion into mitochondrial outer membrane. Located in cytosol and extracellular exosome. Implicated in Chagas disease. Biomarker of chronic obstructive pulmonary disease; rheumatoid arthritis; type 2 diabetes mellitus; and ulcerative colitis. [provided by Alliance of Genome Resources, Apr 2022]

The c.1304A>G (p.Y435C) alteration is located in exon 11 (coding exon 11) of the HSPA4 gene. This alteration results from a A to G substitution at nucleotide position 1304, causing the tyrosine (Y) at amino acid position 435 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
