GeneDx RCV000445120 SCV000520828 likely pathogenic not provided 2016-12-23 criteria provided, single submitter clinical testing The P167L likely pathogenic variant, also reported as P165L, in the MVK gene has been observed previously in patients with Hyper IgD syndrome including in both the homozygous and compound heterozygous states (Simon et al., 2004; de Wolff et al., 2009; Cuisset et al., 2001; Drenth et al., 1999). It was not observed at any significant frequency in approximately 6,500 individuals of European and African American ancestry by the NHLBI Exome Sequencing Project. P167L is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. Although this substitution occurs at a position that is not conserved, in silico analysis predicts this variant is probably damaging to the protein structure/function. Additionally, missense variants in nearby residues (P165L, N166I, G171R) have been reported in the Human Gene Mutation Database in association with MVK-related disorders (Stenson et al., 2014), supporting the functional importance of this region of the protein. Therefore, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded.
