Description

In-frame deletion of 1 amino acid in a non-repeat region predicted to critically alter the protein; Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Identified in patients with MODY in published literature and referred for genetic testing at GeneDx in association with MODY (PMID: 29927023, 24804978); This variant is associated with the following publications: (PMID: 19790256, 27167055, 24804978, 29927023)

Description

DNA sequence analysis of the GCK gene demonstrated a three base pair deletion in exon 6, c.635_637del. This in-frame deletion is predicted to result in the deletion of an amino acid residue, p.Ser212del. This deletion has been previously described in individuals with GCK -related MODY and neonatal hyperglycemia (PMIDs: 24804978, 29927023, 27167055 and 34374989). This sequence change has been described in the gnomAD database with a global population frequency of 0.0004% (dbSNP rs193922314). These collective evidences indicate that this sequence change is likely pathogenic, however functional studies have not been performed to prove this conclusively.
