If Mr. T tests positive for Huntington disease (HD), is it essential to carry out a genetic test by his children? Introduction: Mr. T discovered a potentially overwhelming family history once he learned his brother’s medical diagnosis like dementia, frequency of seizures, and muscular rigidity. At the age of 49, his brother was diagnosed with an inherited medical condition called Huntington disease (HD). He develops primary symptoms at the age of 45 and in the early 60s he died. This incidence helped him to reveal his father’s suicide. Now, Mr. T (38) wonders about his chances of carrying the HD gene. Mr. T and his wife discuss the advantages and disadvantages of undertaking genetic test. This couple has two teenage children (a boy and a girl).
