Genes affected
PRLR (HGNC:9446): (prolactin receptor) This gene encodes a receptor for the anterior pituitary hormone, prolactin, and belongs to the type I cytokine receptor family. Prolactin-dependent signaling occurs as the result of ligand-induced dimerization of the prolactin receptor. Several alternatively spliced transcript variants encoding different membrane-bound and soluble isoforms have been described for this gene, which may function to modulate the endocrine and autocrine effects of prolactin in normal tissue and cancer.

Benign, no assertion criteria providedcurationReproductive Health Research and Development, BGI GenomicsJan 06, 2020NM_000949.5:c.508A>C (Ile170Leu) was reported as I146L in the literature. Bogorad et al. used multiple functional assays, which unambiguously converge to the evidence that I146L exhibits constitutive activity, highlighting the remarkable effect of this single substitution on the biological properties of the PrlR (PMID: 24195502). This variant has an allele frequency of 0.027 in European (non-Finnish) subpopulation in the gnomAD database, including 71 homozygous occurrences. Taken together, we interprete this variant as Benign/Likely benign variant. ACMG/AMP criteria applied: BS1, BS2, PS3. -
