GeneDx RCV000159355 SCV000209301 uncertain significance not provided 2013-01-02 criteria provided, single submitter clinical testing The Ala83Asp variant in the TPM1 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Ala83Asp results in a non-conservative amino acid substitution of a non-polar Alanine with a negatively charged Aspartic acid at a position that is conserved in mammals. A mutation in a nearby codon (Ile92Thr) has been reported in association with cardiomyopathy, supporting the functional importance of this region of the protein. The NHLBI ESP Exome Variant Server reports Ala83Asp was not observed in approximately 6,500 samples from individuals of European and African American backgrounds, indicating it is not a common benign variant in these populations. With the clinical and molecular information available at this time, we cannot definitively determine if Ala83Asp is a disease-causing mutation or a rare benign variant. The variant is found in HCM panel(s).
