Prevalence of SRY and DAX-1 gene deletion in patients with Cryptorchidism and Hypospadias – A Pilot study in North Indian Children

| description | Background: Cryptorchidism and hypospadias are common problems in males attending the pediatric surgery clinic. These two abnormalities are also associated with genetic syndromes/disorders of sexual development (DSD).
Aims and Objectives: Aim of present study was to find out the prevalence of SRY and DAX-1 gene deletions in phenotypic males with cryptorchidism or hypospadias.
Materials and Methods: Children with cryptorchidism, or hypospadias attending the Pediatric Surgery OPD were enrolled for the study after informed consent. One blood sample (4ml) was taken from each patient for DNA analysis and PCR amplification of SRY and DAX-1 genes was done using the previously described primers. PCR for DAX and SRY genes was done according to a standard protocol.
Results: The age ranged from 12 months to 144 months. Twenty-nine children had cryptorchidism and 22 had hypospadias. Out of 29 children having cryptorchidism, 11 had right side cryptorchidism and 7 had bilateral cryptorchidism. Out of 22 children having hypospadias, 13 had distal penile hypospadias. The DNA analysis showed amplification of DAX gene in all 51 patients. SRY gene showed amplification in 50/51 patients and one patient’s DNA did not show amplification.
Conclusion: More extensive studies are needed to explore the enigma of genetic basis involved in DSD. Cryptorchidism and hypospadias are anomalies with potentially severe consequences, such as infertility and testicular cancer, and more research efforts can help in characterization of cause of these abnormalities. |
