Genes affected

RPGRIP1 (HGNC:13436): (RPGR interacting protein 1) This gene encodes a photoreceptor protein that interacts with retinitis pigmentosa GTPase regulator protein and is a key component of cone and rod photoreceptor cells. Mutations in this gene lead to autosomal recessive congenital blindness. [provided by RefSeq, Oct 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

Variant summary: RPGRIP1 c.1753C>T (p.Pro585Ser) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0017 in 248042 control chromosomes, predominantly at a frequency of 0.0028 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 3 fold of the estimated maximal expected allele frequency for a pathogenic variant in RPGRIP1 causing Leber Congenital Amaurosis phenotype (0.0011), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. c.1753C>T has been reported in the literature in individuals affected with Leber Congenital Amaurosis, Primary Open-Angle Glaucoma or Retinitis Pigmentosa (Wiszniewski_2010, Fernndez-Martnez_2011, Ge_2015, Wang_2017). These reports do not provide unequivocal conclusions about association of the variant with Leber Congenital Amaurosis. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Six ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance (n=2) and likely benign (n=4). Based on the evidence outlined above, the variant was classified as likely benign. -
