GeneDx RCV000599389 SCV000710464 likely pathogenic not provided 2018-01-22 criteria provided, single submitter clinical testing The c.188delT variant in the TBX5 gene causes a frameshift starting with codon Leucine 63, changes this amino acid to an Arginine residue and creates a premature Stop codon at position 3 of the new reading frame, denoted p.Leu63ArgfsX3. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The c.188delT variant is not observed in large population cohorts (Lek et al., 2016). Although this variant has not been previously reported to our knowledge, it is a strong candidate for a pathogenic variant. However, the possibility it may be a rare benign variant cannot be excluded.
