Genes affected

PSG7 (HGNC:9524): (pregnancy specific beta-1-glycoprotein 7) This gene is a member of the pregnancy-specific glycoprotein (PSG) gene family. The PSG genes are a subgroup of the carcinoembryonic antigen (CEA) family of immunoglobulin-like genes, and are found in a gene cluster at 19q13.1-q13.2 telomeric to another cluster of CEA-related genes. The PSG genes are expressed by placental trophoblasts and released into the maternal circulation during pregnancy, and are thought to be essential for maintenance of normal pregnancy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014]

Ambry Genetics

Apr 04, 2023

The c.1190G>A (p.R397H) alteration is located in exon 5 (coding exon 5) of the PSG7 gene. This alteration results from a G to A substitution at nucleotide position 1190, causing the arginine (R) at amino acid position 397 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
