Genes affected

HSPA1L (HGNC:5234): (heat shock protein family A (Hsp70) member 1 like) This gene encodes a 70kDa heat shock protein. In conjunction with other heat shock proteins, this protein stabilizes existing proteins against aggregation and mediates the folding of newly translated proteins in the cytosol and in organelles. The gene is located in the major histocompatibility complex class III region, in a cluster with two closely related genes which also encode isoforms of the 70kDa heat shock protein.

Oct 10, 2023

The c.1918G>A (p.V640I) alteration is located in exon 2 (coding exon 1) of the HSPA1L gene. This alteration results from a G to A substitution at nucleotide position 1918, causing the valine (V) at amino acid position 640 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
