Genes affected

ISG15 (HGNC:4053): (ISG15 ubiquitin like modifier) The protein encoded by this gene is a ubiquitin-like protein that is conjugated to intracellular target proteins upon activation by interferon-alpha and interferon-beta. Several functions have been ascribed to the encoded protein, including chemotactic activity towards neutrophils, direction of ligated target proteins to intermediate filaments, cell-to-cell signaling, and antiviral activity during viral infections. While conjugates of this protein have been found to be noncovalently attached to intermediate filaments, this protein is sometimes secreted. [provided by RefSeq, Dec 2012]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BP6: Variant 1-1013973-G-T is Benign according to our data. Variant chr1-1013973-G-T is described in ClinVar as [Likely_benign]. Clinvar id is 2706162.Status of the report is criteria_provided_single_submitter, 1 stars.
