Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004789739 SCV005399896 uncertain significance Maturity-onset diabetes of the young type 2 2024-10-08 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3A. Following criteria are met: 0103 - Loss of function and gain of function are known mechanisms of disease in this gene. Loss of function or inactivating variants are associated with MODY type II (MIM#125851) and diabetes mellitus, permanent neonatal 1 (MIM#606176). Gain of function or activating variants have been associated with hyperinsulinemic hypoglycemia, and usually cluster in a discrete region of the protein termed the allosteric activator site (PMID: 19790256). (I) 0108 - This gene is associated with both recessive and dominant disease. Recessive inheritance is rare, caused by biallelic variants resulting in a more severe and neonatal phenotype (MIM#606176) (OMIM, PMID: 19790256). (I) 0200 - Variant is predicted to result in a missense amino acid change from threonine to methionine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 0600 - Variant is located in the annotated hexokinase 2 domain (DECIPHER). (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
