Introduction: Sickle cell disease (SCD) is a genetic blood disorder caused by a mutation in the HBB gene, which encodes the beta-globin subunit of hemoglobin. This mutation leads to the production of abnormal hemoglobin S (HbS), causing red blood cells to deform into a sickle shape. These deformed cells can block blood flow, leading to complications like chronic hemolysis, anemia, severe pain episodes, and organ damage.

ATP-dependent chromatin remodeling protein ATRX is an essential regulator involved in maintenance of DNA structure and chromatin state and regulation of gene expression during development. ATRX was originally identified as the monogenic cause of X-linked α-thalassemia mental retardation (ATR-X) syndrome. Affected individuals display a variety of developmental abnormalities and skeletal deformities.

Routine serum studies in a female patient with sustained prediabetic glycated hemoglobin A (HbA) levels, controlled on metformin, yielded an unexpected finding: an elevated HbA value of ≥14.9% (≥139 mmol/mol) (normal reference range, <5.7% to <39 mmol/mol).

Objectives: To describe a variant hemoglobin that interferes with HbA analysis by cation exchange HPLC.
Case Presentation: A 78 years-old Spanish male patient visited the Internal Medicine Clinic for a routine check-up, with HbA included to screen for diabetes. He had suffered hypertension and dyslipidemia, and the patient had no previous symptoms suggestive of diabetes such as hyperglycemia, weight loss, polydipsia, polyuria or tiredness.

Background: Strategic action plans around newborn health evaluation are needed, to address the high neonatal mortality rate in Nepal. Surveillance systems, like Newborn Metabolic Screening (NBS), could reveal unrecognized drivers of neonatal death. NBS is not routinely performed in Nepal.
