Genes affected

CGB7 (HGNC:16451): (chorionic gonadotropin subunit beta 7) This gene is a member of the glycoprotein hormone beta chain family and encodes the beta 7 subunit of chorionic gonadotropin (CG). Glycoprotein hormones are heterodimers consisting of a common alpha subunit and an unique beta subunit which confers biological specificity. CG is produced by the trophoblastic cells of the placenta and stimulates the ovaries to synthesize the steroids that are essential for the maintenance of pregnancy. The beta subunit of CG is encoded by 6 genes which are arranged in tandem and inverted pairs on chromosome 19q13.3 and contiguous with the luteinizing hormone beta subunit gene.

Feb 06, 2023

The c.187C>T (p.R63C) alteration is located in exon 3 (coding exon 3) of the CGB7 gene. This alteration results from a C to T substitution at nucleotide position 187, causing the arginine (R) at amino acid position 63 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
