Genes affected

MCRS1 (HGNC:6960): (microspherule protein 1) Enables RNA binding activity and telomerase inhibitor activity. Involved in histone H4 acetylation; negative regulation of DNA metabolic process; and positive regulation of protein localization to nucleolus. Located in cytoplasm; nucleolus; and nucleoplasm. Part of Ino80 complex; MLL1 complex; and histone acetyltransferase complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification
