Question

Quizplus · Accepted Answer

Imprinting refers to the process where certain genes are preferentially expressed from either the maternal or paternal copy of a gene. In the case of HD, if a father inherits the mutant allele from his mother, it is possible that the expression of that allele is influenced by imprinting, leading to an increased risk of passing on the disease to his own children. This is supported by studies that have identified differential gene expression patterns in individuals with HD based on the parent of origin for the mutant allele.
