IPEX syndrome is a rare genetic disorder characterized by severe diarrhea, autoimmune endocrine disorder, and eczematous dermatitis. This case report highlights the importance of relating clinical symptoms to genetic results, as whole genome sequencing was used to diagnose a severe case of IPEX syndrome in a 2-week-old boy.
Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare genetic disorder that typically presents in the first year of life with severe diarrhea, autoimmune endocrine disorder, and inflammatory dermatitis, most commonly an eczematous dermatitis. IPEX syndrome is caused by variants in the FOXP3 gene leading to dysregulation of T-regulatory (Treg) cells and an aberrant immune response. Here, we present a case of severe IPEX syndrome diagnosed following whole genome sequencing (WGS) in a 2-week-old boy with bloody mucoid diarrhea, failure to thrive, and a diffuse eczematous dermatitis. As multiple variants of interest were identified with WGS, this case highlights the importance of relating the clinical symptoms to the genetic results.
