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.

The c.340A>G (p.I114V) alteration is located in exon 4 (coding exon 4) of the HSPA4L gene. This alteration results from a A to G substitution at nucleotide position 340, causing the isoleucine (I) at amino acid position 114 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
