According to the criteria for screening, which condition's carrier frequency is noted as 1/90?

The correct answer pertains to the carrier frequency of Tay-Sachs disease, which has been reported at approximately 1 in 90 for individuals of Ashkenazi Jewish descent, but can also resonate with the screening criteria contextually involving populational carrier rates among other groups involved.

Cystic Fibrosis has a carrier frequency of approximately 1 in 25 among Caucasians, and Spinal Muscular Atrophy (SMA) carriers are around 1 in 40. Gaucher disease has varying carrier frequencies based on ethnicity, typically around 1 in 12 in Ashkenazi Jews, rather than the 1 in 90 figure referenced. Consequently, while the carrier frequency indicated does indeed relate to specific populations, the correct answer is tied specifically to the recognized carrier statistics for Tay-Sachs among Ashkenazi Jewish individuals rather than the options presented here.

The significance of understanding the carrier frequencies aids in implementing effective screening programs and counseling strategies geared toward populations at high risk for particular genetic conditions.
