Genes affected
TCAP (HGNC:11610): (titin-cap) Sarcomere assembly is regulated by the muscle protein titin. Titin is a giant elastic protein with kinase activity that extends half the length of a sarcomere. It serves as a scaffold to which myofibrils and other muscle related proteins are attached. This gene encodes a protein found in striated and cardiac muscle that binds to the titin Z1-Z2 domains and is a substrate of titin kinase, interactions thought to be critical to sarcomere assembly. Mutations in this gene are associated with limb-girdle muscular dystrophy type 2G. [provided by RefSeq, Jul 2008]

not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineSep 24, 2019The c.111-15dupC variant in TCAP is classified as likely benign because it is does not impact the splice consensus sequence and computational splice prediction tools do not predict an impact on splicing. It has been identified in 0.03% (4/14490) of African chromosomes by gnomAD (http://gnomad.broadinstitute.org). ACMG/AMP Criteria applied: BP4, BP7. -
