Genes affected

MYBPC2 (HGNC:7550): (myosin binding protein C2) This gene encodes a member of the myosin-binding protein C family. This family includes the fast-, slow- and cardiac-type isoforms, each of which is a myosin-associated protein found in the cross-bridge-bearing zone (C region) of A bands in striated muscle. The protein encoded by this locus is referred to as the fast-type isoform. Mutations in the related but distinct genes encoding the slow-type and cardiac-type isoforms have been associated with distal arthrogryposis, type 1 and hypertrophic cardiomyopathy, respectively.

The c.411G>T (p.E137D) alteration is located in exon 5 (coding exon 5) of the MYBPC2 gene. This alteration results from a G to T substitution at nucleotide position 411, causing the glutamic acid (E) at amino acid position 137 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
