Continuous variables are given as median and interquartile range, age is given as median (min - max), while categorical variables are given as percentages. *The number excludes one recruited relative with a rare HNF1A allelic variant, but without diabetes.†P-values were calculated using Mann-Whitney U test (significance level α = 0.05); for categorical variables Chi-square (treatment) and Fisher’s (gender) tests were used. NP - statistical analysis was not performed due to too small sample size. BMI - body mass index. HbA1c - glycated haemoglobin. Here, HNF1A is linked to diabetes mellitus.
