The valine at codon 2380 is replaced by methionine, an amino acid with highly similar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.

Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 2e-05 in 247728 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.7138G>A in individuals affected with Adams-Oliver Syndrome 5 and no experimental evidence demonstrating its impact on protein function have been reported. Five ClinVar submitters have assessed the variant since 2014: four classified the variant as uncertain significance and one as benign. Based on the evidence outlined above, the variant was classified as uncertain significance.
