A variant of uncertain significance has been identified in the FGD4 gene. The L110P variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The L110P variant is observed in 35/66728 (0.05%) alleles from individuals of European background (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The L110P variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. However, this substitution occurs at a position that is not conserved. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
