A novel mutation in the SLCO2A1 gene presenting as persistent hypoproteinaemia and refractory iron deficiency anaemia due to chronic enteropathy: a case report. BMC Pediatrics, 24(1). https://doi.org/10.1186/s12887-024-05252-6 ‌1471-2431 (Electronic)http://repository.kln.ac.lk/handle/123456789/28994Indexed in MEDLINE.BACKGROUND The SLCO2A1 gene encodes a prostaglandin transporter and we report a novel mutation causing hypoproteinaemia and refractory anaemia due to chronic enteropathy.Case PRESENTATION An 18-year-old boy of consanguineous parents was investigated for hypoproteinaemia and anaemia. He was short, pale and had generalised oedema. Investigations revealed haemoglobin 5.8 g/dL; hypochromic microcytic anaemia; low serum protein, albumin, globulin, ferritin and iron. Bone marrow aspiration revealed low iron stores. Upper and lower gastrointestinal endoscopies showed moderate gastritis, duodenitis, and non-specific patchy inflammation in the rectum. The whole exome sequencing revealed a homozygous missense mutation in SCLO2A1 gene (NP_005621.2:p.Arg97Cys; rs761212094). Sanger sequencing of the sibling with milder phenotype revealed same homozygous mutation, and carrier father was heterozygous.CONCLUSION We report a novel mutation of SLCO2A1 gene causing severe persistent hypoproteinaemia and refractory iron deficiency anaemia due to chronic enteropathy helping to delineate genotype-phenotype correlation of SLCO2A1 variants.enSLCO2A1Chronic enteropathyHypoproteinaemiaRefractory iron deficiency anaemiaArticle
