RCV000194380 | SCV000052540 | benign | not specified | 2025-01-08 | criteria provided, single submitter | clinical testing | Variant summary: GCK c.46-12C>T alters a non-conserved nucleotide located at a position not widely known to affect splicing. Consensus agreement among computation tools (TraP) 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 0.0038 in 250260 control chromosomes, predominantly at a frequency of 0.0051 within the Non-Finnish European subpopulation in the gnomAD database, including 2 homozygotes. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 204-fold of the estimated maximal expected allele frequency for a pathogenic variant in GCK causing maturity-onset diabetes of the young type 2 phenotype (2.5e-05). c.46-12C>T has been reported in the literature (PMID: 8454109, 8433729, 8068341). These report(s) do not provide unequivocal conclusions about association of the variant with maturity-onset diabetes of the young type 2. The following publications have been ascertained in the context of this evaluation (PMID: 8454109, 8433729, 8068341, 7555485, 16963153, 18271687). ClinVar contains an entry for this variant (Variation ID: 36222). Based on the evidence outlined above, the variant was classified as benign. |

RCV000029885 | SCV000469453 | benign | Maturity-onset diabetes of the young 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 and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. |
