Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard RCV001005014 SCV001164576 pathogenic Leber congenital amaurosis 6 2018-12-03 criteria provided, single submitter research The heterozygous c.3238+1G>A variant in RPGRIP1 was identified by our study, in the compound heterozygous state, along with another pathogenic variant, in two siblings with Leber congenital amaurosis (PMID: 30072743). The c.3238+1G>A variant in RPGRIP1 has not been previously reported in individuals with Leber congenital amaurosis and was absent from large population studies. This variant occurs in the invariant region (+/- 1/2) of the splice consensus sequence and is predicted to cause altered splicing leading to a frameshift and an abnormal or absent protein. Loss of function of the RPGRIP1 gene is an established disease mechanism in autosomal recessive Leber congenital amaurosis. The presence of this variant in combination with a reported pathogenic variant and in an individual with Leber congenital amaurosis increases the likelihood that the c.3238+1G>A variant is pathogenic. In summary, this variant meets criteria to be classified as pathogenic for Leber congenital amaurosis in an autosomal recessive manner based on the predicted impact of the variant and occurrence with pathogenic RPGRIP1 variant in an individual with Leber congenital amaurosis. ACMG/AMP Criteria applied: PM2, PVS1, PM3 (Richards 2015).
