SCD SD Punjab is the third most common genotype of SCD in Oman and is associated with several serious complications. The aim of the study is to establish the clinical and laboratory features of SCD patients with SD double heterozygotes and study the impact of haemoglobin F, hydroxyurea, and other modulators on the disease severity.</p><p><strong>Methods: </strong>We analysed the electronic medical records of 52 consecutive SCD patients who were diagnosed as double heterozygote SD Punjab between 2006 and 2022. The study was approved by the local medical research and ethics committee. The data captured included SCD-related complications and current clinical and laboratory indices.

SCD-related complications included Acute Chest Syndrome (ACS) (48%), Gall stones (26.9%), Avascular necrosis (AVN) (28.8%), Stroke (13.5%) and splenic sequestration (7.7%), whereas 5 (9.6%) patients of this cohort died. Surgical and Autosplenectomy were seen in 18 (34.6%).
