Summary Introduction

To review:

Genetic testing for human hereditary conditions for identification of heterozygous carriers.

Introduction:

Genetic testing for the heterozygous carrier is a practice of detecting the people for the possibility of conceiving progenies affected by recessive diseases. The recessive inheritance is characterized by one having the disease receiving two mutated copies of alleles- one from the mother and another from the father. The heterozygotes for the disease generally are carriers for the disease. The genetic testing of human hereditary conditions for identification of heterozygous carriers helps a couple before conception to decide the possible preventive measures, genetic diagnosis, or early prenatal diagnostic testing.
