Genes affected

ZAR1 (HGNC:20436): (zygote arrest 1) This maternal effect gene is oocyte-specific and encodes a protein that is thought to function in the initiation of embryogenesis. A similar protein in mouse is required for female fertility. [provided by RefSeq, Jul 2013]

The c.271G>A (p.G91R) alteration is located in exon 1 (coding exon 1) of the ZAR1 gene. This alteration results from a G to A substitution at nucleotide position 271, causing the glycine (G) at amino acid position 91 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
