Cytopenia - NOT Fanconi anaemia
Gene: RPS20Comment on list classification: Rating Amber as currently only two unrelated cases reported with DBA in association with variants in the RPS20 gene (PMID:32790018).Created: 9 Oct 2020, 12:52 p.m. | Last Modified: 9 Oct 2020, 12:52 p.m.
Panel Version: 1.27
Two unrelated cases where a de novo variant involving Ile84 (Ile84Ser and Ile84Asn), and reduce the RPS20 protein level in patient cells. Yeast models with mutation of the cognate residue resulted in defects in growth, ribosome biogenesis, and polysome formation. Loss of function may not be the mechanism of disease, because loss of function variants appear to be exclusively associated with familial colorectal cancer without the DBA phenotype.
