HTT gene CAG repeats [Presence] in Amniotic fluid or Chorionic villus sample by Molecular genetics method

HTT gene CAG Rpt Amn/CVS Ql

Definition

  • Prenatal diagnosis of Huntington disease (HD) by detecting the presence of a CAG expansion in the HTT gene in amniotic fluid or chorionic villus sample (CVS). This test may be performed when there is a family history of a CAG expansion.
