One of these patients had a third HMCN1 variant (rs780673178), and for the second patient, we discovered additional variants in COL8A2 (rs771963014) and ABCA4 (rs62654395, described as pathogenic in autosomal recessive macular degeneration, such as Stargardt disease and cone–rod dystrophy, and this was submitted by Fulgent Genetics Laboratory as pathogenic in AMD). Here, ABCA4 is linked to Stargardt disease.
