INTRODUCTION: Hajdu-Cheney syndrome is a rare disorder caused by truncation mutations in exon 34 of the NOTCH2 gene. The main presentation includes acro-osteolysis, osteoporosis, and dysmorphism. This syndrome affects the other body systems as well.
CASE PRESENTATION: We report a case of a 6-year-old female that initially developed polyhydramnios and short upper limbs as a fetus. In addition, the patient had multiple anomalies as a neonate, including dysmorphism, congenital heart disease, hearing loss, recurrent respiratory tract infections, skeletal abnormalities, renal cysts, and hypertension. She continues to receive multidisciplinary care, and the finding of a C.7021C > T: P.Q2341x mutation in exon 34 of the NOTCH2 gene confirms the diagnosis. To our knowledge, this is the first case to report this variant in the literature.
DISCUSSION: Because of the rarity of this syndrome and its diverse presentation, a high index of suspicion accompanied by genetic testing is paramount for diagnosing Hajdu-Cheney syndrome. We recommend a multidisciplinary approach for these patients to provide the highest possible quality of care.
