Quest Diagnostics has announced the US launch of QHerit™, a genetic screening service that helps people of multiple ethnicities identify their risk of passing on heritable disorders to their offspring.
The QHerit Pan-Ethnic Expanded Carrier Screen is a panel of tests for the 22 heritable diseases cited in new screening guidelines from the American College of Gynecology (ACOG).
Among the diseases are alpha-thalassemia, Fanconi anemia, and beta-hemoglobinopathies, including sickle cell disease (SCD).
Traditionally, genetic carrier screening has been used for at-risk populations based on specific ancestry assumptions and focused on only a few likely disorders with higher prevalence associated with that ethnicity.
In its new guidelines, ACOG recommends offering pan-ethnic, expanded carrier, and ethnic-specific screening for all women considering pregnancy. The guidelines also state that the partner of a woman who tests positive may be a candidate for screening.
QHerit screens women and men for clinically relevant variants of genes for disorders that could have potentially devastating consequences, result in early death, or create a need for significant early intervention.
The disorders covered by QHerit include:
| Disease | Race/ethnicity | |||
| Alpha-thalassemia | Mediterranean, Middle East, Southeast Asian, African, Chinese, Asian Indian | |||
