Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV003486521 SCV004240906 pathogenic Holt-Oram syndrome 2023-12-12 criteria provided, single submitter clinical testing Variant summary: TBX5 c.529delC (p.His177ThrfsX10) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant was absent in 251440 control chromosomes. To our knowledge, no occurrence of c.529delC in individuals affected with Holt-Oram Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as pathogenic.
