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 ( rs1554948310) in MODY yet. - |
