Variant summary
Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM1PM2PM5PP3_Moderate
The NM_000545.8(HNF1A):c.710A>C(p.Asn237Thr) 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. Variant has been reported in ClinVar as Uncertain significance (★★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N237D) has been classified as Likely pathogenic.

Monogenic diabetes Uncertain:1
Uncertain significance, reviewed by expert panel | curation | ClinGen Monogenic Diabetes Variant Curation Expert Panel | Apr 12, 2022 | The c.710A>C variant in the HNF1 homeobox A gene, HNF1A, causes an amino acid change of asparagine to threonine at codon 237 (p.(Asn237Thr)) of NM_000545.8. This variant is located within a conserved region of the DNA binding domain (codons 107-174 and 201-280) of HNF1A, which is defined as critical for the protein’s function by the ClinGen MDEP (PM1_Supporting). This variant is absent from gnomAD v2.1.1 (PM2_Supporting). This variant is predicted to be deleterious by computational evidence, with a REVEL score of 0.888, which is greater than the MDEP threshold of 0.70 (PP3). Another missense variant, c.709A>G (p.Asn237Asp), has been classified as likely pathogenic by the ClinGen MDEP (PM5_Supporting). In summary, c.710A>C meets the criteria to be classified as a variant of uncertain significance for monogenic diabetes. ACMG/AMP criteria applied, as specified by the ClinGen MDEP (specification version 1.1, approved September 30, 2021): PM1_Supporting, PM2_Supporting, PM5_Supporting, PP3. - |
Maturity onset diabetes mellitus in young Other:1
Uncertain risk allele, criteria provided, single submitter | research | Clinical Genomics, Uppaluri K&H Personalized Medicine Clinic | - | Mutations in HNF1A gene can predispose to MODY3. It is associated with both micro and macrovascular complications of diabetes, especially cardiovascular complications. Associated with glucosuria. May respond well to sulfonylureas. However, more evidence is required to confer the association of this particular variant rs1555211935 with MODY3. - |
