Diabetes mellitus
En stofskifteforstyrrelse, kendetegnet ved unormalt høje blodsukkerniveauer på grund af nedsat insulinproduktion eller insulinresistens/desensibilisering.
- 1 GenCC-indsender vurderer den som definitiv eller stærk
Hvad viden ændrer
Teplizumab (Tzield) ved præsymptomatisk T1D i stadie 2 (godkendt af FDA i 2022); insulinbehandling ved klinisk T1D-debut; TrialNet-screening for autoantistoffer hos højrisikoslægtninge; lukkede insulinsystemer (closed-loop)
Sådan læser en genomtest MT-TL1
12
positioner i MT-TL1, hvor ClinVar klassificerer en ændring som patogen eller sandsynligvis patogen
Ingen af dem ligger i en region, som korte læsninger har svært ved.
