Description

The Q223H variant in the RASA1 gene has been reported previously in an individual with neurofibromatosis, however this individual also had an NF1 nonsense variant (Maruoka et al., 2014). The Q223H variant is not observed in large population cohorts (Lek et al., 2016). The Q223H variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. 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.We interpret Q223H as a variant of uncertain significance.
