This varaint is denoted c.3190+4 C>T: IVS29+4 C>T in intron 29 of the MYBPC3 gene (NM_000256.3). The c.3190+4 C>T variant in the MYBPC3 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Several in silico algorithms predict that this variant destroys the splice donor site in intron 29, resulting in abnormal gene splicing which may lead to either an abnormal message that is subject to nonsense-mediated mRNA decay or to an abnormal protein product if the message is used for protein translation. A nearby intronic mutation c.3190+5 G>A, has been reported in association with HCM (Rodriguez-Garcia M et al., 2010). Other splice site mutations in the MYBPC3 gene have been reported in association with HCM. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. The variant is found in HCM panel(s).
