Meiosis is generally a fair process: each chromosome has a 50% chance of being included into each gamete. However, meiosis can become aberrant with some chromosomes having a higher chance of making it into gametes than others. Yet, why and how such systems evolve remains unclear.

Myeloproliferative neoplasms (MPNs) are clonal hematopoietic stem cell disorders commonly characterized by excessive production of blood cell lineages. The JAK2 V617F mutation plays a crucial role in the pathogenesis of these conditions, often leading to thrombotic complications. Here, we present the case of a 21-year-old man who presented with acute abdominal pain and was found to have portal vein thrombosis with splenomegaly.

Blood clots are complex structures composed of blood cells and proteins held together by the structural framework provided by an insoluble fibrin network. Factor (F)XIII is a protransglutaminase essential for stabilizing the fibrin network. Activated FXIII(a) introduces novel covalent crosslinks within and between fibrin and other plasma and cellular proteins, and thereby promotes fibrin biochemical and mechanical integrity.

Autosomal recessive proximal renal tubular acidosis (AR-pRTA) with ocular abnormalities is a rare syndrome caused by variants in the SLC4A4 gene, which encodes Na/HCO3 cotransporter (NBCe1). The syndrome primarily affects the kidneys, but also causes extra-renal manifestations. Pancreatic type NBCe1 is located at the basolateral membrane of the pancreatic ductal cells and together with CFTR chloride channel, it is involved in bicarbonate secretion.
