Genes affected

XPR1 (HGNC:12827): (xenotropic and polytropic retrovirus receptor 1) The protein encoded by this gene is a receptor for the xenotropic and polytropic classes of murine leukemia viruses. The encoded protein is involved in phosphate homeostasis by mediating phosphate export from the cell. Defects in this gene have been associated with idiopathic basal ganglia calcification-6. [provided by RefSeq, Jun 2016]

XPR1 Gene-Disease associations (from GenCC):

• basal ganglia calcification, idiopathic, 6

  Inheritance: AD Classification: STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), Illumina, Genomics England PanelApp, PanelApp Australia, Ambry Genetics
• bilateral striopallidodentate calcinosis

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

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=-0.86).
