Genes affected
CAPN3 (HGNC:1480): (calpain 3) Calpain, a heterodimer consisting of a large and a small subunit, is a major intracellular protease, although its function has not been well established. This gene encodes a muscle-specific member of the calpain large subunit family that specifically binds to titin. Mutations in this gene are associated with limb-girdle muscular dystrophies type 2A. Alternate promoters and alternative splicing result in multiple transcript variants encoding different isoforms and some variants are ubiquitously expressed. [provided by RefSeq, Jul 2008]

ACMG classification
Classification made for transcript
Verdict is Uncertain_significance. Variant got 5 ACMG points.
PM1
?
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 8 uncertain in NM_000070.3
PM2
?
Very rare variant in population databases, with high coverage;
PM4
?
Nonframeshift variant in NON repetitive region in NM_000070.3. Strenght limited to Supporting due to length of the change: 1aa.
