Genes affected

ETAA1 (HGNC:24648): (ETAA1 activator of ATR kinase) Enables protein serine/threonine kinase activator activity. Involved in several processes, including positive regulation of protein serine/threonine kinase activity; regulation of DNA damage checkpoint; and replication fork processing. Located in cytosol; nuclear replication fork; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.32240653).
