Genes affected

PLET1 (HGNC:30053): (placenta expressed transcript 1) Predicted to be involved in negative regulation of cell-matrix adhesion; positive regulation of cell migration; and wound healing, spreading of epidermal cells. Predicted to be located in extracellular region and plasma membrane. Predicted to be active in apical plasma membrane and external side of plasma membrane.

PTS (HGNC:9689): (6-pyruvoyltetrahydropterin synthase) The enzyme encoded by this gene catalyzes the elimination of inorganic triphosphate from dihydroneopterin triphosphate, which is the second and irreversible step in the biosynthesis of tetrahydrobiopterin from GTP. Tetrahydrobiopterin, also known as BH(4), is an essential cofactor and regulator of various enzyme activities, including enzymes involved in serotonin biosynthesis and NO synthase activity. Mutations in this gene result in hyperphenylalaninemia. [provided by RefSeq, Oct 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.781 is higher than 0.05.
