Clinical Validity Scoring Notes and points

Variant/Case Evidence:

PMID: 25042156

  • Infant with Diamond-Blackfan anemia had a deletion on chromosome 2 encompassing RPL31

  • Studying human CD34+ hematopoietic progenitors demonstrated that RPL31 is required for steps in the maturation of 60S ribosomal subunits in patient cells and that decreased expression of RPL31 in human CD34+ hematopoietic progenitors interferes with erythroid differentiation

  • 0.5 + 0.5 (functional data) = 1 pt
