Abstract EN
Familial glucocorticoid deficiency is a rare autosomal recessive genetic disorder which belongs to a group of primary adrenal insufficiency (PAI) and is mainly caused by mutations in the MC2R and MRAP genes.
A comprehensive search was conducted to find the reported variants of MC2R and MRAP genes.
In silico pathogenic analysis was performed for the reported variants.
PCR amplification and sequencing were performed for three patients.
Structural analysis, modeling, and interactome analysis were applied to characterize novel MC2R variants and their proteins.
About 80% of MC2R-related cases showed the clinical symptoms which were diagnosed at <2 years old.
107 patients had MC2R mutations (85 homozygotes, 21 compound heterozygotes, and 1 simple heterozygote).
59 variants were found in the MC2R gene.
Four mutations were responsible for half of patients.
39 homozygous patients had MRAP mutations; 14 variants were determined in the MRAP gene.
Nine proteins were predicted by STRING to associate with the studied proteins.
Two novel MC2R variants, c.128T > G (p.Leu43Arg) and c.251T > A (p.Ile84Asn), were found in two patients at the age of above and below 2 years, respectively.
Mutations in MC2R and MRAP genes are the main cause of FGD.
Genetic studies and in silico analysis will help to confirm the diagnosis.
