RCV001100633 | SCV001257161 | uncertain significance | Hyperprolinemia type 2 | 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. |

RCV003987783 | SCV004803701 | likely benign | not specified | 2024-01-23 | criteria provided, single submitter | clinical testing | Variant summary: ALDH4A1 c.1460+15C>T alters a non-conserved nucleotide located at a position not widely known to affect splicing. Consensus agreement among computation tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.00026 in 251432 control chromosomes. To our knowledge, no occurrence of c.1460+15C>T in individuals affected with Deficiency of pyrroline-5-carboxylate reductase and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 876152). Based on the evidence outlined above, the variant was classified as likely benign. |
