Reproductive Health Research and Development, BGI Genomics RCV000074480 SCV001142344 benign Multiple fibroadenoma of the breast 2020-01-06 no assertion criteria provided curation NM_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.
