Genes affected

HSPA4L (HGNC:17041): (heat shock protein family A (Hsp70) member 4 like) The protein encoded by this gene is heat shock inducible and may act as a chaperone. The encoded protein can protect the heat-shocked cell against the harmful effects of aggregated proteins. This gene is highly expressed in leukemia cells and may be a good target for therapeutic intervention. Several transcripts encoding different isoforms have been found for this gene.

Nov 18, 2022

The c.252G>T (p.R84S) alteration is located in exon 3 (coding exon 3) of the HSPA4L gene. This alteration results from a G to T substitution at nucleotide position 252, causing the arginine (R) at amino acid position 84 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
