PMID: 36745868 report two distantly related patients (last common ancestor 5 generations prior) with the same homozygous missense variant, G348R. The variant is absent from gnomAD, although the residue is not conserved in mammals. Both patients experienced severe recurrent infection, neurologic and hematologic disorders, and gastroenteropathy. Functional studies on patient lymphocytes were consistent with reduced transporter activity.
PMID: 36517554 report two cousins with immunodeficiency with the same G348R variant as above. Functional studies on patient cells supported loss of transporter function. The patient’s symptoms ameliorated, and hematological and immunological tests normalized in the 2nd month of folinic acid supplementation.
