The DNA Diagnostic & Research Laboratory (DDRL) at KK Women’s and Children’s Hospital has been dedicated to providing high quality DNA-based testing for the molecular diagnosis, carrier testing and prenatal testing of genetic disorders, for over 10 years. Mutation detection methods used in the laboratory include automated capillary-based sequencing and genotyping, PCR, multiplex ligation-dependent probe amplification and Southern techniques. The laboratory currently provides DNA tests for over 10 genetic diseases, with continuous development of new tests and implementation of improved testing methodologies.
