GeneDx RCV000494201 SCV000581723 likely pathogenic not provided 2013-08-05 criteria provided, single submitter clinical testing The K13E missense change in the ABCA4 gene has not been reported as a pathogenic variant or as a benign polymorphism to our knowledge. The K13E amino acid substitution is non-conservative with a positively charged residue (Lys) being replaced by a negatively charged residue (Glu). The residue at which this substitution occurs is highly conserved in the ABCR protein. According to the Human Gene Mutation Database (HGMD), other missense mutations (L11P, R18W) have been reported in nearby residues (Stenson, 2009). The K13E variant was not observed in approximately 6,500 individuals of European and African American ancestry in an external variant database, indicating it is not a common benign variant in these populations. Therefore, the K13E missense change is a candidate for a pathogenic variant, although the possibility that it is a benign polymorphism cannot be completely excluded.
