Trichorhinopharyngeal Syndrome Type 1 and Trisomy 21: A Patient with 2 Genetic Mutations
Publication/Presentation Date

Abstract
Trichorhinophalangeal syndrome (TRPS) Type I is a rare, autosomal dominant genetic syndrome with a spectrum of characteristics affecting hair, craniofacial, and skeletal development. It was first described in 1966 by Giedion based on three main features of sparse hair, bulbous nasal tip, and short deformed fingers. TRPS Type I is generally associated with mutations or microdeletions in the TRPS1 gene on chromosome 8q23.3, with translocations on this chromosomal arm also reported. The prevalence of TRPS Type I is unknown due to varying and subtle presenting features. Approximately 100 cases of TRPS Type I and III and 100 cases of TRPS Type II have been described and published up until 2017. We describe the neonatal course of an infant with TRPS Type I and Trisomy 21, two chromosomal anomalies prenatally diagnosed. To our knowledge, this is the first report of TRPS with Trisomy 21.
