Invitae RCV003698744 SCV004467856 uncertain significance not provided 2023-05-20 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with asparagine, which is neutral and polar, at codon 390 of the GCK protein (p.Ile390Asn). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of maturity onset diabetes of the young (MODY) (Invitae). ClinVar contains an entry for this variant (Variation ID: 36183). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GCK 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.
