Genes affected

ZAN (HGNC:12857): (zonadhesin) This gene encodes a protein that functions in the species specificity of sperm adhesion to the egg zona pellucida. The encoded protein is located in the acrosome and may be involved in signaling or gamete recognition. An allelic polymorphism in this gene results in both functional and frameshifted alleles; the reference genome represents the functional allele. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2015]

The c.904G>T (p.A302S) alteration is located in exon 8 (coding exon 7) of the ZAN gene. This alteration results from a G to T substitution at nucleotide position 904, causing the alanine (A) at amino acid position 302 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
