Genes affected

HEBP2 (HGNC:15716): (heme binding protein 2) The protein encoded by this gene is found predominately in the cytoplasm, where it plays a role in the collapse of mitochondrial membrane potential (MMP) prior to necrotic cell death. The encoded protein enhances outer and inner mitochondrial membrane permeabilization, especially under conditions of oxidative stress. [provided by RefSeq, May 2016]

The c.541A>G (p.S181G) alteration is located in exon 4 (coding exon 4) of the HEBP2 gene. This alteration results from a A to G substitution at nucleotide position 541, causing the serine (S) at amino acid position 181 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
