Genes affected

OXT (HGNC:8528): (oxytocin/neurophysin I prepropeptide) This gene encodes a precursor protein that is processed to produce oxytocin and neurophysin I. Oxytocin is a posterior pituitary hormone which is synthesized as an inactive precursor in the hypothalamus along with its carrier protein neurophysin I. Together with neurophysin, it is packaged into neurosecretory vesicles and transported axonally to the nerve endings in the neurohypophysis, where it is either stored or secreted into the bloodstream. The precursor seems to be activated while it is being transported along the axon to the posterior pituitary. This hormone contracts smooth muscle during parturition and lactation. It is also involved in cognition, tolerance, adaptation and complex sexual and maternal behaviour, as well as in the regulation of water excretion and cardiovascular functions.

Ambry Genetics

Jan 26, 2022

The c.290G>A (p.R97H) alteration is located in exon 2 (coding exon 2) of the OXT gene. This alteration results from a G to A substitution at nucleotide position 290, causing the arginine (R) at amino acid position 97 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
