**Core Concept**
Genomic imprinting is an epigenetic phenomenon where the expression of a gene is influenced by its parental origin. This means that some genes are imprinted to be expressed only from the maternal or paternal allele, leading to distinct phenotypes based on the parental contribution.

**Why the Correct Answer is Right**
Genomic imprinting is crucial in the development and growth of the embryo. Disorders related to genomic imprinting occur due to the imbalance of imprinted genes, which can lead to various developmental and growth abnormalities. For instance, Prader-Willi syndrome and Angelman syndrome are two classic disorders related to genomic imprinting. Prader-Willi syndrome is caused by the loss of function of paternally imprinted genes on chromosome 15, whereas Angelman syndrome is caused by the loss of function of maternally imprinted genes on chromosome 15.

**Why Each Wrong Option is Incorrect**
**Option A:** Not a disorder related to genomic imprinting.
**Option B:** Not a disorder related to genomic imprinting.
**Option C:** Not a disorder related to genomic imprinting.
**Option D:** Not a disorder related to genomic imprinting.

**Clinical Pearl / High-Yield Fact**
Classic human disorders related to genomic imprinting include Prader-Willi syndrome and Angelman syndrome, highlighting the importance of considering the parental origin of imprinted genes in the diagnosis and management of these conditions.

**Correct Answer:** A, B, C. None of the above disorders are directly related to genomic imprinting.
