The clinical impact of carrier testing for lysosomal storage diseases

The effects of lysosomal storage diseases (LSDs) can be devastating. However, some LSDs have available treatments that can prevent or delay symptoms and prolong survival when administered early in life. Learn more about carrier frequency for these diseases and the impact of carrier testing.

Our goal was to assess the positivity rate of carrier testing for LSDs in the general population and within various ethnic groups.

We performed a retrospective analysis of >230,000 patients referred for carrier testing, which included assessment for between one to 25 LSDs using Progenity’s Preparent® Carrier Test.

What did we find?

  • In this analysis, we found at least 2.77%, or approximately 1 in 36 individuals, to be carriers of an LSD.1
  • 60.5% of LSD carriers were positive for an LSD with an existing treatment.1
  • Identifying pregnancies affected by LSDs with treatment options can enable therapy to begin earlier, and may lead to better patient outcomes.
