84 In addition, CFTR panels being used have insufficient mutations to allow the detection of minority populations with uncommon CF-causing mutations that can cause inequities in NBS, such as M1101K (c.3302T>A), more commonly found in Hutterite populations,26 and H199Y (c.595C>T) and S492F (c.1475C>T), more commonly found in Hispanic populations.
