Genes affected

SMC2 (HGNC:14011): (structural maintenance of chromosomes 2) Predicted to enable ATP binding activity; chromatin binding activity; and single-stranded DNA binding activity. Involved in mitotic chromosome condensation. Located in condensed chromosome; cytoplasm; and nuclear lumen. Part of condensin complex. [provided by Alliance of Genome Resources, Apr 2022]

SMC2-DT (HGNC:50827): (SMC2 divergent transcript)

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=-0.84).
