Genes affected
MRAP (HGNC:1304): (melanocortin 2 receptor accessory protein) This gene encodes a melanocortin receptor-interacting protein. The encoded protein regulates trafficking and function of the melanocortin 2 receptor in the adrenal gland. The encoded protein can also modulate signaling of other melanocortin receptors. Mutations in this gene have been associated with familial glucocorticoid deficiency type 2. Alternatively spliced transcript variants have been described. [provided by RefSeq, Dec 2009]

Glucocorticoid deficiency 2 Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Aug 28, 2014 | The Met1? variant has been identified in 0.012% (1/8600) of European American chromosomes and 0.023% (1/4406) of African American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs80358231). The Met1? variant in MRAP has also been reported in at least 8 individuals with familial glucocorticoid deficiency (Metherell 2005). All these individuals were homozygous for the variant. This missense variant alters the evolutionary conserved initiating methionine and is predicted to lead to abnormal or absent protein. In summary, this variant meets our criteria to be classified as pathogenic for familial glucocorticoid deficiency with recessive inheritance. - |
