Three different groups reported the molecular genetic basis for Smith-Lemli-Opitz syndrome simultaneously. Smith-Lemli-Opitz syndrome is caused by mutations in the DHCR7 gene, the gene that codes for the enzyme DHCR7 that normally converts 7DHC to cholesterol in the final step of the cholesterol synthetic pathway.
About inheritance and genetics: Inheritance of Dissociative Identity Disorder refers to whether the condition is inherited from your parents or runs in families. The level of inheritance of a condition depends on how important genetics are to the disease.Strongly genetic diseases are usually inherited, partially genetic diseases are sometimes inherited, and non-genetic diseases are not inherited.he level of inheritance of a condition depends on how important genetics are to the disease. Strongly genetic diseases are usually inherited, partially genetic diseases are sometimes inherited, and non-genetic diseases are not inherited.
15 IDENTITY DISORDER BRAIN CORRELATES Lehmann, Faber, Achermann, Jeanmonod, Gianotti, and Pizzagalli (2001), recorded EEG and low resolution electromagnetic tomography (LORETA) from a participant in advanced meditation, demonstrating some interesting results that may be relevant to dissociative disorders.6 IDENTITY DISORDER BRAIN CORRELATES substantia nigra (SN), which is implicated in the processes of movement and posture. Perhaps a person with DID experiences a very quick and subtle shutting down of the bodyâs positioning while switching occurs, preparing for the new identity state to take control.
