ABSTRACT
Objective: The aim of this work was to report a case of an Emirati child who presented with developmental delay and multiple congenital abnormalities that are consistent with distal arthrogryposis type 5D
Clinical Presentation and Intervention: The clinical presentation comprised contractures of the shoulders, elbows, and knees in addition to camptodactyly and neck pterygium. The facial dysmorphic features noted include ptosis and microretrognathia. Importantly, left orchidopexy was also observed and corrected surgically. Whole exome sequencing revealed that the patient is homozygous for the novel c.1184+1G>T variant in endothelin-converting enzyme-like 1 [ECEL1]
Conclusion: This is a case of a novel homozygous splice site mutation in the ECEL1 gene in a child with a phenotype consistent with distal arthrogryposis type 5D. The child was born to consanguineous Emirati parents heterozygous for the novel ECEL1 mutation
