Genes affected

CRHBP (HGNC:2356): (corticotropin releasing hormone binding protein) Corticotropin-releasing hormone is a potent stimulator of synthesis and secretion of preopiomelanocortin-derived peptides. Although CRH concentrations in the human peripheral circulation are normally low, they increase throughout pregnancy and fall rapidly after parturition. Maternal plasma CRH probably originates from the placenta. Human plasma contains a CRH-binding protein which inactivates CRH and which may prevent inappropriate pituitary-adrenal stimulation in pregnancy. [provided by RefSeq, Jul 2008]

The c.176G>A (p.R59Q) alteration is located in exon 3 (coding exon 3) of the CRHBP gene. This alteration results from a G to A substitution at nucleotide position 176, causing the arginine (R) at amino acid position 59 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
