Illumina Laboratory Services, Illumina	RCV000265968	SCV000381602	uncertain significance	Meckel syndrome, type 4	2018-01-12	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.

Labcorp Genetics (formerly Invitae), Labcorp	RCV001347198	SCV001541447	uncertain significance	Familial aplasia of the vermis; Meckel-Gruber syndrome; Nephronophthisis	2024-01-19	criteria provided, single submitter	clinical testing	This sequence change affects codon 453 of the CEP290 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the CEP290 protein. This variant also falls at the last nucleotide of exon 14, which is part of the consensus splice site for this exon. This variant is present in population databases (rs779195306, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with CEP290-related conditions. ClinVar contains an entry for this variant (Variation ID: 310620). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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.

PreventionGenetics, part of Exact Sciences	RCV004732843	SCV005346236	uncertain significance	CEP290-related disorder	2024-07-30	no assertion criteria provided	clinical testing	The CEP290 c.1359G>A variant is not predicted to result in an amino acid change (p.=). This variant is predicted to alter splicing based on available splicing prediction programs (Alamut Visual v2.11). To our knowledge, this variant has not been reported in the literature in patients with CEP290-related disorders. This variant is reported in 0.020% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
