RCV000332042 | SCV000439174 | uncertain significance | ALG12-congenital disorder of glycosylation | 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. |

RCV004701434 | SCV005204447 | likely benign | not specified | 2024-06-11 | criteria provided, single submitter | clinical testing | Variant summary: ALG12 c.501C>T alters a non-conserved nucleotide resulting in a synonymous change. 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 0.00058 in 244784 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in ALG12 causing ALG12-Congenital Disorder Of Glycosylation, allowing no conclusion about variant significance. To our knowledge, no occurrence of c.501C>T in individuals affected with ALG12-Congenital Disorder Of Glycosylation and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 342051). Based on the evidence outlined above, the variant was classified as likely benign. |
