Background: Hemoglobin (Hb) J-Cubujuqui is a rare Hb variant, and reports about it are very limited. There are no descriptions that it affects the results of glycated Hb.
Methods: In this study, we describe a rare variant discovered during newborn screening. Both high-performance liquid chromatography (HPLC) and capillary electrophoresis for hemoglobin analysis displayed abnormal peaks. The Hb variant was confirmed by Sanger sequencing.
Results: The pedigree study shows the variant was inherited from the newborn's father. His fasting blood glucose (FBG) level was 5.5 mmol/L. HbA1c measured by HPLC was falsely low in her father (2.41%), whereas that measured by immunoassay was normal (5.11%). Sanger sequencing revealed a heterozygous mutation (CGT˃AGT) at amino acid position 141 of the α1 gene, corresponding to Hb J-Cubujuqui [α1 141(HC3) Arg→Ser (CGT˃AGT); HBA1:c.424C˃A (or HBA2)].
Conclusions: This is the first report that Hb J-Cubujuqui interferes with the measurement of HbA1cand prompts clinicians to pay attention to the accuracy of glycated Hb results.

Background: The α-actinin-4 (ACTN4) gene encodes an actin-binding protein, which plays a crucial role in maintaining the structure and function of podocytes. Previous studies have confirmed that ACTN4 mutations can lead to focal segmental glomerulosclerosis-1 (FSGS1), a rare disease primarily manifesting in adolescence or adulthood, characterized by mild to moderate proteinuria, with some cases progressing slowly to end-stage renal disease.
Case Presentation: We report a 12.

Background: Among childhood cancer survivors, germline rare variants in autosomal dominant cancer susceptibility genes (AD CSGs) could increase subsequent neoplasm (SNs) risks, but risks for rarer SNs and by age at onset are not well understood.
Methods: We pooled the Childhood Cancer Survivor Study and St Jude Lifetime Cohort (median follow-up = 29.7 years, range 7.

Background: Neonatal diabetes mellitus (NDM) is a rare monogenic disorder, typically diagnosed within the first six months of life. While NDM is well-recognized globally, data from India regarding its clinical characteristics, treatment strategies, and long-term outcomes are scarce.
Objectives: To describe the molecular characterization, clinical phenotype and follow-up of children with NDM.

Undifferentiated carcinomas with osteoclast-like giant cells of the pancreaticobiliary tract (UCOGCs) are rare but distinctive tumors with limited literature. To study the clinicopathologic characteristics of UCOGCs including morphology, immunohistochemistry (IHC), management, and survival outcomes. Assessment of 12 patients of UCOGC found over 10 years from a tertiary care oncology center database.

Acetylesterase, produced by , plays a crucial role in deacetylating hemicellulose during pulp production. Thermostable variants of this enzyme, although rare, can significantly enhance industrial efficiency by retaining activity at high temperatures. This research aims to design a thermostable variant of acetylesterase from (EC 3.
