Genes affected
NPB (HGNC:30099): (neuropeptide B) This gene encodes a member of the neuropeptide B/W family of proteins and preproprotein that is proteolytically processed to generate multiple protein products. The encoded products include neuropeptide B-23 and a C-terminally extended form, neuropeptide B-29, which are characterized by an N-terminal brominated tryptophan amino acid. Both of the encoded peptides bind with higher affinity to neuropeptide B/W (NPB/W) receptor 1 compared to the related NPB/W receptor 2. These peptides may regulate feeding, pain perception, and stress in rodents. [provided by RefSeq, Jul 2015]
PCYT2 (HGNC:8756): (phosphate cytidylyltransferase 2, ethanolamine) This gene encodes an enzyme that catalyzes the formation of CDP-ethanolamine from CTP and phosphoethanolamine in the Kennedy pathway of phospholipid synthesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]
PCYT2 Gene-Disease associations (from GenCC):
  • spastic paraplegia 82, autosomal recessive
