Genes affected

OVGP1 (HGNC:8524): (oviductal glycoprotein 1) This gene encodes a large, carbohydrate-rich, epithelial glycoprotein with numerous O-glycosylation sites located within threonine, serine, and proline-rich tandem repeats. The gene is similar to members of the mucin and the glycosyl hydrolase 18 gene families. Regulation of expression may be estrogen-dependent. Gene expression and protein secretion occur during late follicular development through early cleavage-stage embryonic development. The protein is secreted from non-ciliated oviductal epithelial cells and associates with ovulated oocytes, blastomeres, and spermatozoan acrosomal regions. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 05, 2024

The c.1552A>G (p.T518A) alteration is located in exon 11 (coding exon 11) of the OVGP1 gene. This alteration results from a A to G substitution at nucleotide position 1552, causing the threonine (T) at amino acid position 518 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
