Genes affected

TAC3 (HGNC:11521): (tachykinin precursor 3) This gene encodes a member of the tachykinin family of secreted neuropeptides. The encoded preproprotein is proteolytically processed to generate the mature peptide, which is primarily expressed in the central and peripheral nervous systems and functions as a neurotransmitter. This peptide is the ligand for the neurokinin-3 receptor. This protein is also expressed in the outer syncytiotrophoblast of the placenta and may be associated with pregnancy-induced hypertension and pre-eclampsia. Mutations in this gene are associated with normosmic hypogonadotropic hypogonadism. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Feb 2016]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BP6: Variant 12-57015484-A-G is Benign according to our data. Variant chr12-57015484-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 1187691.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High Homozygotes in GnomAd4 at 4 AR gene
