Genes affected

HSPB7 (HGNC:5249): (heat shock protein family B (small) member 7) This gene encodes a small heat shock family B member that can heterodimerize with similar heat shock proteins. Defects in this gene are associated with advanced heart failure. In addition, the encoded protein may be a tumor suppressor in the p53 pathway, with defects in this gene being associated with renal cell carcinoma. [provided by RefSeq, Mar 2017]

The c.241G>A (p.A81T) alteration is located in exon 2 (coding exon 2) of the HSPB7 gene. This alteration results from a G to A substitution at nucleotide position 241, causing the alanine (A) at amino acid position 81 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
