Rare anaemia

Gene: RPL17

Green List (high evidence)

The rating of this gene has been updated to green following NHS Genomic Medicine Service approval.

The GMS reviewers noted that it would be appropriate to add this gene with green rating to R92 Rare anaemia in addition to R91 Cytopenia - NOT Fanconi anaemia.

Comment on list classification: As reviewed by Dmitrijs Rots, there are two unrelated pedigrees and functional evidence available in support of the association of this gene to phenotype. Hence, this can be promoted to green rating in the next GMS update.

PMID:39088281 reported two different pedigrees identified with monoallelic variants in RPL17 gene (3C>G & c.452delC/ p.(Thr151Argfs*25). Affected individuals from both pedigrees exhibited clinical features and erythroid proliferation defects consistent with Diamond-Blackfan anaemia. Individuals from first family also presented with skeletal abnormalities, which were not reported in family 2. Modelling of rpl17 deficiency in zebrafish recapitulated the major clinical features of the disorder including anaemia and micrognathia. There is also functional evidence available from lymphoblastoid cell lines (LCLs) derived from patients, which displayed a ribosomal RNA maturation defect reflecting haploinsufficiency of RPL17.

This gene has not yet been associated with relevant phenotypes either in OMIM or in Gene2Phenotype.

Green List (high evidence)

PMID: 39088281 described 2 families with Diamond-Blackfan anemia & functional data. Enough evidence for the green rating.
probably gene should be added also to other panels (like limb disorders; hematological malignancies).
