Introduction & Aims

Effective research into understanding the aetiology of Disorders of Sex Development (DSDs), as well as long-term outcome of these rare conditions, requires multicentre collaboration often across national boundaries and across multiple clinical and research disciplines.

Between 2008 and 2011, the DSD Registry was at the heart of the EuroDSD collaboration for supporting the sharing of data. This Virtual Research Environment will continue to form a platform for research in DSD under funding from MRC.

The Registry adheres to the highest standards of data governance and security and has attracted much interest, changing from a European initiative to an international activity

Description of cases in the Register

At last review (Sept, 2012) there were 1050 cases on the Register, added by registered users from 20 centres in 14 countries across 3 continents (Figure 1)

A further 33 centres and 14 countries have registered as users (with intentions to upload cases or conduct resear4ch studies) covering all 6 habitable continents

The age of first presentation ranges from <1 month to 53 years with a median age of presentation of 10 years, the median year of birth was 1995 (range 1927-2011)

59% (n=616) cases were assigned female sex and 41% (n=434) were assigned male sex

There was a history of infertility or parental consanguinity in 7%(n=77) and 10% (n=107) respectively

Figure 1: Map showing countries & date of joining

Associated malformations were present in 25% (n=261) cases

The commonest disorder type on the Register continues to be disorders of androgen action (n=309) followed by disorders of gonadal development (n=241) (Figure 2)

There were 19 males with 46XX karyotype on the Register and 410 females with 46XY karyotype

A sex chromosome abnormality was found in 1% (n=11) cases

The majority of cases had a 46XY karyotype (n=760), followed by a 46XX karyotype (n=188)

Mosaicism was present in 6% (n=61) cases

Samples are available in 40% (n=420) cases

Conclusions

The Registry is continuing to grow and provide a platform for international collaborative research on these rare disorders

The I-DSD Registry is open to new researchers and clinical contributors and interested parties can register to use the Registry at www.i-dsd.org

In case of enquiries please contact the I-DSD Project Manager, Jillian Bryce ([email protected])
