Clinical Genomics, Uppaluri K&H Personalized Medicine Clinic	RCV001089451	SCV004174201	uncertain significance	Diabetes mellitus, permanent neonatal 4		criteria provided, single submitter	research	Potent mutations in the INS gene can cause early onset diabetes mellitus which is insulin dependent. May have poor response to sulfonylureas, mutations in this gene can cause beta cell destruction.Sufficient evidence is found to confer the association of this particular variant G32S/rs80356664 with Neonatal diabetes.
Invitae	RCV001775542	SCV004294055	pathogenic	not provided	2023-12-30	criteria provided, single submitter	clinical testing	This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 32 of the INS protein (p.Gly32Ser). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with autosomal dominant permanent neonatal diabetes mellitus (PMID: 17855560). In at least one individual the variant was observed to be de novo. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 21122). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects INS function (PMID: 19952343). For these reasons, this variant has been classified as Pathogenic.
