The DAAM2 c.11G>A variant is predicted to result in the amino acid substitution p.Arg4His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.030% of alleles in individuals of East Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
