Improvement of and setting standards for clinical phenotyping, building structures to collect well-phenotyped patient groups, e.g. based on testicular histology.
Prof. Frank Tüttelmann’s reproductive genetics institute aims to identify novel genetic causes for male infertility and deepen the understanding of male germ cells. The multidisciplinary team includes clinician scientists, biomedical researchers, graduate students of several disciplines, and bioinformaticians.
The group focusses on the genetic causes of severe spermatogenic failure, mostly severe oligo- and azoospermia, and some specific defects of sperm function such as CatSper deficiency. Since 2017, Frank is the coordinator of the DFG-funded Clinical Research Unit (CRU) 326 – Male Germ Cells: from Genes to Function. The main goal of the CRU is to significantly reduce the current number of unexplained male infertility cases by assigning more causal genetic diagnoses and, in parallel, improving phenotyping of these patients. For the clinical characterisation, recruitment of patients, and many research questions, the reproductive genetics group closely collaborates with the local Centre of Reproductive Medicine and Andrology (CeRA), most importantly Profs. Jörg Gromoll, Timo Strünker, Sabine Kliesch, and Stefan Schlatt.
As a result of the Male Reproductive Genomics (MERGE) study comprising exome data of more than 1000 infertile men, the group described a number of relevant genes such as TEX11, DMRT1, STAG3, M1AP, SYCP2 and specified associated phenotypes. To facilitate efficient data access and interpretation, the Male Fertility Gene Atlas (MFGA) – a public online platform for OMICs data on male infertility – has been developed by a multidisciplinary team of physicians, biologists and computer scientists.
