Genes affected

GXYLT2 (HGNC:33383): (glucoside xylosyltransferase 2) The protein encoded by this gene is a xylosyltransferase that elongates O-linked glucose bound to epidermal growth factor (EGF) repeats. The encoded protein catalyzes the addition of xylose to the O-glucose-modified residues of EGF repeats of Notch proteins. [provided by RefSeq, Sep 2016]

ENSG00000310267 (HGNC:):

PPP4R2 (HGNC:18296): (protein phosphatase 4 regulatory subunit 2) The protein encoded by this gene is a regulatory subunit of the serine/threonine-protein phosphatase 4 complex. In addition to being required for efficient DNA double strand break repair, this complex plays a role in organization of microtubules at centrosomes and processing of spliceosomal snRNPs. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2015]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
