The carrier frequency in Jews of Eastern and Central European (Ashkenazi) ancestry is about 1/30, while the carrier frequency in non-Jews is unknown. If both parents are carriers, there is a one in four, or 25%, chance with each pregnancy for an affected child. Genetic counseling and genetic testing is recommended for families who may be carriers of<unk> . Worldwide, there have been approximately 600 diagnoses recorded since discovery of the disease, with approximately 350 of them still living.
