Chromosome 15 encodes over 700 genes and comprises nearly 3% of the human genome. CHRFAM7A, a fusion protein comprised of FAM7A and AChR alpha7, is encoded by the CHRFAM7A gene, which is located on a region of human chromosome 15 that is associated with several neuropsychiatric disorders, such as schizophrenia and bipolar affective disorder. CHRFAM7A, also known as D-10 or CHRNA7, is a 412 amino acid multi-pass membrane protein that belongs to the nicotinic acetylcholine receptor (nAChR) subfamily of ligand-gated ion channel proteins, a protein superfamily that mediates signal transmission at synapses. CHRFAM7A is expressed in the hippocampus. Alternative splicing of the CHRFAM7A gene produces two splice variants.
