A member asked:
Just wondering do saliva samples for dna testing tell you about inherited blood disorders? thinking about buying 23andme kit
A doctor has provided 1 answer
And waste $189 ?: The kit tests for 10 of the 400 mutations of the HBB gene that cause Beta-Thalassemia if inherited from both parents & for Sickle-Cell trait. Seek pre-pregnancy genetic counselling from your OB/GYN about your family's inheritable genetic disorder so (s)he can decide if you need a Chromosomal Microarray &/or Hemoglobin Electrophoresis, or a specific molecular genetic test &/or other studies.
