Imprinting Disorders
BWS is categorized as an imprinting disorder, wherein gene expression is regulated by the parent of origin. Abnormalities in genomic imprinting lead to the manifestation of the syndrome. In healthy individuals, certain genes may be active only when inherited from one parent. However, in BWS, loss of imprinting may occur, leading to the inappropriate expression of genes from both alleles, which can cause overgrowth and disordered metabolism.
The primary genes affected include those within the 11p15 region, particularly 9 and IGF2. The loss of imprinting and abnormal expression elevate cancer risk, a concern that clinicians must prioritize in patient management. Furthermore, an understanding of these imprinting mechanisms is vital for genetic counseling, as the patterns may affect familial recurrence risks.
Current research focuses on understanding the molecular mechanisms of imprinting disorders, as this knowledge can guide therapeutic strategies and interventions. Not only does this assist in preventing potential complications, but it also plays a role in psychological counseling for families, as they comprehend the heritable elements involved.
