Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 4P and 4B. PM1PM2BP4_Strong

The NM_020366.4(RPGRIP1):ā€‹c.3766C>Gā€‹(p.Leu1256Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000249 in 1,608,956 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Synonymous variant affecting the same amino acid position (i.e. L1256L) has been classified as Likely benign.

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]

Leber congenital amaurosis 6;C2750720:Cone-rod dystrophy 13 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeSep 06, 2022In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 534364). This variant has not been reported in the literature in individuals affected with RPGRIP1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1256 of the RPGRIP1 protein (p.Leu1256Val). -
