Genes affected

VN1R1 (HGNC:13548): (vomeronasal 1 receptor 1) Pheromones are chemical signals that elicit specific behavioral responses and physiologic alterations in recipients of the same species. The protein encoded by this gene is similar to pheromone receptors and is primarily localized to the olfactory mucosa. An alternate splice variant of this gene is thought to exist, but its full length nature has not been determined. [provided by RefSeq, Jul 2008]

The c.277G>A (p.A93T) alteration is located in exon 1 (coding exon 1) of the VN1R1 gene. This alteration results from a G to A substitution at nucleotide position 277, causing the alanine (A) at amino acid position 93 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
