Variant summary
Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM1PM2PP3_Strong
The NM_000352.6(ABCC8):c.4349T>C(p.Leu1450Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. L1450L) has been classified as Likely benign.

Maturity onset diabetes mellitus in young Uncertain:1
Uncertain significance, criteria provided, single submitter | research | Clinical Genomics, Uppaluri K&H Personalized Medicine Clinic | - | Mutations in ABCC8 gene are associated with both neonatal diabetes mellitus as well as MODY. Patients with this mutation may have a better response to sulfonylureas. However, no sufficient evidence is found to ascertain the role of this particular variant ( rs1554904565) in MODY yet. - |
Hyperinsulinemic hypoglycemia, familial, 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Counsyl | Oct 27, 2017 | - - |
Transitory neonatal diabetes mellitus Uncertain:1
