Molecular analysis of disorders of gonadal development
Zusammenfassung der Projektergebnisse
POF/ODG: By using commercially available arrays 133 novel CNVs were detected in a cohort of 153 patients (96 POF and 57 ODG). Three recurrent CNVs delineate novel candidate genes for POF/ODG. - Using customized arrays 20 potentially pathogenic rearrangements in WT1, NANOS3, FIGLA, LARS2, DMRT1 and DIAPH2 were found. We can show that mutations of LARS2 are not only associated with Perrault syndrome but also in non-syndromic POF. - Gene panel analysis results in the identification of the causative mutation in 24% of the analysed patients. Our findings emphasize the role of STAG3, HFM1, LARS2, SF1, FSHR, MCM8 and WT1 for POF/ODG. Furthermore, we provide evidence for digenic inheritance in some cases (heterozygosity for FSHR and SF1 mutation in one patient, heterozygosity for FSHR and FSHB mutation in another patient) in POF/ODG. XY-GD: We could show that mutations of WT1 cause not only XY gonadal dysgenesis bot also isolated hypospadias or cryptorchidism. - SF1 mutations are detected in 7% of XY GD and in patients with severe oligozoospermia and azoospermia. - We could show that DMRT1 mutations are not only associated with XY GD but also with ovotestis and male infertility. - We provide evidence that different CNVs upstream of SOX9 cause XY GD or SRY-negative XX-maleness.
