Description

The D1058Y variant has not been published as a pathogenic variant, nor has it been reported as a benign polymorphism to our knowledge. The D1058Y variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The D1058Y variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. Additionally, this substitution occurs at a position that is conserved across species and in silico analysis predicts this variant is probably damaging to the protein structure/function. Furthermore, missense variants in nearby residues (R1053Q, E1056D, G1057S, G1057D) have been reported in association with cardiomyopathy, supporting the functional importance of this region of the protein. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
