Genes affected

GPR152 (HGNC:23622): (G protein-coupled receptor 152) Enables identical protein binding activity. Predicted to be involved in G protein-coupled receptor signaling pathway. Predicted to be located in plasma membrane. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

CABP4 (HGNC:1386): (calcium binding protein 4) This gene encodes a member of the CABP family of calcium binding protein characterized by four EF-hand motifs. Mutations in this gene are associated with congenital stationary night blindness type 2B. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]

CABP4 Gene-Disease associations (from GenCC):

• cone-rod synaptic disorder, congenital nonprogressive

  Inheritance: AR Classification: DEFINITIVE, STRONG Submitted by: Labcorp Genetics (formerly Invitae), G2P
