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.579G>T (p.E193D) alteration is located in exon 6 (coding exon 6) of the HSPA4L gene. This alteration results from a G to T substitution at nucleotide position 579, causing the glutamic acid (E) at amino acid position 193 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
