RCV001122615 | SCV001281344 | likely benign | Cone-rod dystrophy 5 | 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 and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. |

RCV001236602 | SCV001409334 | uncertain significance | not provided | 2024-11-18 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 340 of the PITPNM3 protein (p.Arg340Trp). This variant is present in population databases (rs776506570, gnomAD 0.006%). This missense change has been observed in individual(s) with clinical features of retinal dystrophy (internal data). ClinVar contains an entry for this variant (Variation ID: 888971). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on PITPNM3 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. |
