Genes affected

CAPN1 (HGNC:1476): (calpain 1) The calpains, calcium-activated neutral proteases, are nonlysosomal, intracellular cysteine proteases. The mammalian calpains include ubiquitous, stomach-specific, and muscle-specific proteins. The ubiquitous enzymes consist of heterodimers with distinct large, catalytic subunits associated with a common small, regulatory subunit. This gene encodes the large subunit of the ubiquitous enzyme, calpain 1. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Nov 2010]

The c.174T>G (p.D58E) alteration is located in exon 2 (coding exon 1) of the CAPN1 gene. This alteration results from a T to G substitution at nucleotide position 174, causing the aspartic acid (D) at amino acid position 58 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
