Genes affected

RRS1 (HGNC:17083): (ribosome biogenesis regulator 1 homolog) Enables 5S rRNA binding activity. Involved in several processes, including mitotic metaphase plate congression; protein localization to nucleolus; and ribosomal large subunit assembly. Located in condensed nuclear chromosome; nucleolus; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

RRS1-DT (HGNC:50465): (RRS1 divergent transcript)

LOC102724687 (HGNC:):

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.34).
• BP7: Synonymous conserved (PhyloP=2.68 with no splicing effect.
