Case Report: Thanatophoric dysplasia

Abstract

Thanatophoric dysplasia (TD) is a rare and lethal skeletal dysplasia caused by a de novo mutation in the fibroblast growth factor receptor 3 gene (FGFR3), with a frequency range of 1 in 20,000 to 50,000. We report a case of a 19-year-old primigravida from rural Nepal who presented with ultrasonographic findings suggestive of TD at 26 weeks and three days of gestation. The pregnancy was terminated due to the lethal nature of the condition. Accurate prenatal diagnosis and comprehensive counselling are paramount for families affected by this condition. This case has been reported due to its rarity, with the aim of raising awareness among healthcare professionals about this devastating condition.
