Table 1.
Number of new diagnoses of type 2 diabetes, CFRD and MD made in the study centres during the analysed period
| Variable | Lodz (Lodzkie voivodeship) | Katowice (Slaskie voivodeship) | Gdansk (Pomorskie voivodeship) | Overall |
|---|---|---|---|---|
| Number of new type 2 diabetes diagnoses | 3 | 8 | 14 | 25 |
| Number of new CFRD diagnoses | 4 | 10 | 4 | 15 |
| Number of MD diagnoses | ||||
| MODY | 26 | 35 | 29 | 90 |
| GCK | 25 | 32 | 27 | 84 |
| HNF1A/4A | 1 | 3 | 0 | 4 |
| Other | 0 | 0 | 2 | 2 |
| Neonatal diabetes | 3 | 1 | 3 | 7 |
| WFS and ALMS | 2 and 1 | 0 | 0 | 3 |
| Median delay between diagnosis of diabetes and genetic testing (25–75%) (years) | 1.27 (0.21–4.65) | 0.80 (0.16–1.64) | 0.73 (0.22–2.39) | 0.84 (0.19–2.70) |
| Median age of patients with MD at genetic examination (25–75%) (years) | 10.10 (3.12–16.21) | 10.86 (7.33–17.55) | 13.79 (6.21–16.89) | 11.05 (6.65–16.56) |
Duration of the delay between the diagnosis of diabetes and referral for genetic tests did not differ between study centres, probands or siblings, nor between patients with positive and negative genetic test results, and was not correlated with the year of the study (all p values >0.2 in Mann–Whitney U test)
ALMS, Alström syndrome; WFS, Wolfram syndrome
