Gene: AP4B1

Alternate names for this Gene: BETA-4|CPSQ5|SPG47

Gene Summary: This gene encodes a subunit of a heterotetrameric adapter-like complex 4 that is involved in targeting proteins from the trans-Golgi network to the endosomal-lysosomal system. Mutations in this gene are associated with cerebral palsy spastic quadriplegic type 5 (CPSQ5) disorder. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Gene is located in Chromosome: 1

Location in Chromosome : 1p13.2

Description of this Gene: adaptor related protein complex 4 subunit beta 1

Type of Gene: protein-coding
