SEMG2
semg2 Gene: An Essential Player in Human Health
Description:
The semg2 gene encodes a protein called SEMG2, which is located on chromosome 5q31.1. It plays a crucial role in the normal development and function of the nervous system. SEMG2 is a member of the SAM and SH3 domain-containing proteins (SASH) family and is involved in various cellular processes, including cell signaling, cytoskeletal organization, and transcriptional regulation.
Associated Diseases:
Mutations in the semg2 gene have been linked to several neurological disorders, including:
- Charcot-Marie-Tooth Disease Type 4C (CMT4C): A genetic disorder characterized by progressive weakness and atrophy of the muscles in the hands, feet, and legs.
- Hereditary Motor and Sensory Neuropathy Type VIIA (HMSN VIIA): A rare form of CMT4C that affects the peripheral nerves and causes muscle weakness and sensory loss.
- Distal Hereditary Motor Neuropathy Type VII (dHMN VII): A type of motor neuropathy that primarily affects the lower limbs, causing progressive weakness and atrophy.
- Spinal Muscular Atrophy with Lower Extremity Predominance (SMALED): A rare form of spinal muscular atrophy characterized by severe muscle weakness and wasting in the lower extremities.
Did you Know ?
Approximately 1 in 20,000 individuals worldwide are affected by CMT4C, which is caused by mutations in the semg2 gene.
