Gene Gene information from NCBI Gene database.
Entrez ID 10939
Gene name AFG3 like matrix AAA peptidase subunit 2
Gene symbol AFG3L2
Synonyms (NCBI Gene)
OPA12SCA28SPAX5
Chromosome 18
Chromosome location 18p11.21
Summary This gene encodes a protein localized in mitochondria and closely related to paraplegin. The paraplegin gene is responsible for an autosomal recessive form of hereditary spastic paraplegia. This gene is a candidate gene for other hereditary spastic parapl
