Genes affected

MRGPRX3 (HGNC:17980): (MAS related GPR family member X3) This gene encodes a member of the mas-related/sensory neuron specific subfamily of G protein coupled receptors. The encoded protein may be involved in sensory neuron regulation and in the modulation of pain. [provided by RefSeq, Oct 2009]
