Illumina Laboratory Services, Illumina	RCV000321854	SCV000397817	uncertain significance	Joubert syndrome 7	2018-01-13	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

GeneDx	RCV000224936	SCV001811744	uncertain significance	not provided	2024-10-03	criteria provided, single submitter	clinical testing	In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Labcorp Genetics (formerly Invitae), Labcorp	RCV001854774	SCV002269455	uncertain significance	Familial aplasia of the vermis; Meckel-Gruber syndrome	2022-10-13	criteria provided, single submitter	clinical testing	This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 579 of the RPGRIP1L protein (p.Tyr579Cys). This variant is present in population databases (rs148230131, gnomAD 0.07%). This variant has not been reported in the literature in individuals affected with RPGRIP1L-related conditions. ClinVar contains an entry for this variant (Variation ID: 235333). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RPGRIP1L protein function. In 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.

Ambry Genetics	RCV002519757	SCV003678643	likely benign	Inborn genetic diseases	2023-08-21	criteria provided, single submitter	clinical testing	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

PreventionGenetics, part of Exact Sciences	RCV004529383	SCV004106136	uncertain significance	RPGRIP1L-related disorder	2024-01-08	no assertion criteria provided	clinical testing	The RPGRIP1L c.1736A>G variant is predicted to result in the amino acid substitution p.Tyr579Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.076% of alleles in individuals of African descent in gnomAD, which may be too common to be an undocumented primary cause of disease. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
