An overgrowth syndrome caused by imprinting defects at chromosome 11p15. Most cases are sporadic; familial cases with CDKN1C mutations exist.
How Genetic Is Beckwith-Wiedemann Syndrome?
Beckwith-Wiedemann Syndrome has a strong genetic basis. Research estimates heritability at approximately 100%, meaning genetic factors account for the majority of variation in whether individuals develop this condition.
Key genes associated with Beckwith-Wiedemann Syndrome: IGF2 CDKN1C H19. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
