Gene: [01q21/IGHGR1A] immunoglobulin G Fc-receptor Ia (high-affinity); high-affinity p72 Fc/gamma-R protein (IgG receptor Ia); [FCGR1A FCGR1 ]

FAG |
[1] Two other IgG Fc receptors (low-affinity) have been identified and
mapped: Fc-gamma II (protein p40; GEM:01q23/IGHGR2A) and Fc-gamma III
(protein p50-70; GEM:01q23/IGHGR3A). Their
cDNAs are cloned. All the
three proteins belong to the multigene superfamily of
immunoglobulin-like peptides; see FAM:IMM/00.0.
[2] The following IgG Fc receptors are identified: high-affinity 1 receptor (Fc-gamma I, protein 72; this gene, as well as GEM:01p12/IGHGR1B, GEM:01q21/IGHGR1C); low-affinity 2 receptor (Fc-gamma II, protein p40; see GEM:01q23/IGHGR2A and GEM:01q23/IGHGR2B); low-affinity 3 receptor (Fc-gamma III, protein p50-70; see GEM:01q23/IGHGR3A and GEM:01q23/IGHGR3B)." |

Alterations of the structure or expression of IGHG receptors are probably involved in pathogenesis of systemic lupus erythematosis (Frank-1979)." |
