Abstract:
A male full-term neonate was admitted at 30 minutes of life with pallor and 10 minutes of respiratory distress. Physical examination revealed pallor, increased intercanthal distance, low-set ears, a palpable cystic mass in the neck, hepatomegaly, a pedunculated, globular appendage attached to the right thumb, and an ectopic toenail on the right second toe. Laboratory testing showed severe anemia with hemoglobin of 44 g/L. Bone marrow examination demonstrated hypoplasia. Whole-exome sequencing identified a heterozygous pathogenic variant in the RPS19 gene, c.175T>C (p.Ser59Pro), establishing the diagnosis of Diamond-Blackfan anemia. On follow-up to 2 years and 2 months of age, both hemoglobin and reticulocyte counts remained within normal ranges. This case illustrates early-onset severe anemia in a neonate with genetically confirmed Diamond-Blackfan anemia and expands the phenotypic spectrum, informing clinical recognition and management.
