Genes affected

NT5E (HGNC:8021): (5'-nucleotidase ecto) The protein encoded by this gene is a plasma membrane protein that catalyzes the conversion of extracellular nucleotides to membrane-permeable nucleosides. The encoded protein is used as a determinant of lymphocyte differentiation. Defects in this gene can lead to the calcification of joints and arteries. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2011]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.7).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.562 is higher than 0.05.
