Mutation analysis of the HNF1A gene. Panel (A) Pedigree of the family F3 identified with HNF1A variant (NM_000545.8: c.293C>T, p.Ala98Val). OHA, oral hypoglycemic agents; NT, not tested; n.a, Not available. M and N denote mutant and wild-type alleles, respectively. The age of diabetes onset, treatment follow-up, and last HbA1c measurement are indicated directly below the genotype (were available). Panel (B) Electropherograms showing co-segregation of the heterozygous variant c.293C>T in HNF1A gene to the phenotype observed in the proband and his father. Proband III.1 and his father II.10 carry heterozygous alleles (C/T) linked to the phenotype whereas non-affected subjects (mother II.9 and siblings III.2, III.3) carry homozygous alleles (C/C). Mutated nucleotide on the chromatographs is depicted with an arrow. Amino acid substitution is indicated in red.
