Abstract
Syndrom renálních cyst a diabetu (RCAD), zvaný také HNF1B-MODY či MODY5, je způsoben delecí nebo bodovou mutací genu HNF1B, která vede k depleci transkripčního faktoru HNF1B. Hlavními klinickými součástmi RCAD jsou cystické onemocnění ledvin nebo jiné vývojové anomálie ledvin a diabetes mellitus, který se projeví nejčastěji ve 2. dekádě života nebo později. Poruchy ledvin mohou vést k rozvoji chronické renální insuficience už v dětství nebo mladé dospělosti. K dalším příznakům patří poruchy funkce jater – cholestatický ikterus ve středním věku, ale někdy už novorozenecká cholestáza, atrofie pankreatu s poruchou exokrinní sekrece a některé vrozené anomálie pohlavního ústrojí. Na rozdíl od ostatních forem MODY diabetu rodinná anamnéza nemusí být pozitivní, protože většina odchylek HNF1B vzniká de novo. Na RCAD pomýšlíme zejména u dospělých osob s diabetem a cystickým onemocněním ledvin nebo cholestatickým ikterem a u dětí s cystickým onemocněním ledvin nejasné etiologie, i bez přítomnosti diabetu. Podpůrným nálezem může být hypomagneziemie, která se vyskytuje až u 70 % nositelů poruchy genu HNF1B, a hyperurikemie. Klíčová slova: diabetes mellitus – cholestatický ikterus – HNF1B – MODY – RCAD
The renal cysts and diabetes syndrome (RCAD), also known as HNF1B-MODYor MODY5, is caused by the deletion or point mutation of HNF1B gene which leads to the depletion of HNF1B transcription factor. The main clinical components of RCAD include cystic kidney disease or other developmental anomalies of the kidneys and diabetes mellitus which typically manifests in the second decade of life or later. Renal disorders may lead to the development of chronic renal insufficiency already in childhood or young adulthood. The other symptoms include hepatic impairment - cholestatic jaundice in middle-aged patients, sometimes even neonatal cholestasis, atrophy of the pancreas with the impairment of exocrine pancreatic secretion and some congenital anomalies of the genital tract. As opposed to the other forms of MODY diabetes, the family history may not be positive because most of the deviations of HNF1B appear de novo. We associate RCAD in particular with adults suffering from diabetes and cystic kidney disease and/or cholestatic jaundice and children with cystic kidney disease of unclear etiology, even without the presence of diabetes. A supportive finding may be hypomagnesemia which occurs in up to 70 % of patients diagnosed with HNF1B related disease and hyperuricemia. Key words: HNF1B – MODY – RCAD – diabetes mellitus – cholestatic jaundice
