Member Description



Prof. Krausz leads two research groups with longstanding expertise in molecular genetics of different pathological conditions affecting males (spermatogenic disturbances, cryptorchidism, testis cancer, central hypogonadism). Her team combines clinical andrology with translational research. The laboratory was the promoter/coordinator of several multicentre studies aimed at defining the role of Y chromosome rearrangements/haplogroups and a number of autosomal and X-linked genetic risk factors in relationship with male infertility and cryptorchidism.

During the last 4 years, research has been mainly focusing on exome analyses in highly selected NOA patients and in familial cases of testis cancer (patient-parent trios).  Exome analysis in SCOS patients has allowed the identification of a high-risk group (based on testis histology and blood analysis) for occult Fanconi Anemia (FA). This finding has major clinical relevance since FA is a cancer-prone disease (Krausz, Riera-Escamilla et al Genetics in Medicine, 2018, in press). The recently performed whole X-chromosome sequencing allowed the identification of recurrent X-linked genetic factors in NOA with potential diagnostic relevance.  In addition to the exome studies, the team is currently performing molecular studies aimed at evaluating the effect of cytotoxic treatments on sperm genome and epigenome in patients affected by testis cancer and haematological malignancies. The Florence laboratory is a reference lab for EMQN for the analysis of AZF deletions and Prof Krausz is the first author of the EAA/EMQN Guidelines on Y chromosome microdeletion analysis (Krausz et al Andrology. 2014;2(1):5-19). 

Prof. Krausz is a clinical andrologist (specialized in endocrinology) and obtained her PhD in Human Genetics (Pasteur Institute/Université Paris VII). Prof Krausz was the PI of the Florence Unit of the “Reprotrain” Marie Curie Network supported by the EU (2012 -2016). She has started a collaboration with the Andrology Department of Fundacio Puigvert in 2008 and since than the two laboratories exchange fellows, students and share all clinical and molecular data. The team participates in the GEMINI project.
