Genes affected

SRI (HGNC:11292): (sorcin) This gene encodes a calcium-binding protein with multiple E-F hand domains that relocates from the cytoplasm to the sarcoplasmic reticulum in response to elevated calcium levels. In addition to regulating intracellular calcium homeostasis it also modulates excitation-contraction coupling in the heart. Alternative splicing results in multiple transcript variants encoding distinct proteins. Multiple pseudogenes exist for this gene. [provided by RefSeq, Mar 2012]

Collection Method: clinical testing

The c.241A>G (p.M81V) alteration is located in exon 4 (coding exon 4) of the SRI gene. This alteration results from a A to G substitution at nucleotide position 241, causing the methionine (M) at amino acid position 81 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
