Menkes disease is an X-linked copper deficiency disorder caused by ATP7A mutations. It causes severe neurodegeneration and characteristic kinky sparse hair.
How Genetic Is Menkes Disease?
Menkes Disease 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 Menkes Disease: ATP7A. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
