The Trps1 gene codes for an atypical member of the GATA type family of transcription factors. Mutations in human TRPS1 lead to the tricho-rhino-phalangeal syndrome types I and III, which are characterized by craniofacial and skeletal abnormalities and disturbed hair development. Correspondingly, during mouse embryonic development strong Trps1 expression is found in the cartilage condensations, ...

EM: erythema multiforme HSV: herpes simplex virus JAK-STAT: Janus kinaseesignal transducer and activator of transcription TRPS: tricho-rhino-phalangeal syndrome INTRODUCTION Erythema multiforme (EM) is an acute, typically self-limited mucocutaneous eruption characterized by distinctive target lesions. In a subset of patients, EM has a more chronic course, with recurrent episodes or even persist...

The tricho-rhino-phalangeal syndrome (TRPS) type I is a rare genetic disorder related to the TRPS1 gene mutation in chromosome 8, characterized by craniofacial abnormalities and disturbances in formation and maturation of bone matrix. The hallmarks are sparse and brittle hair, tendency to premature baldness, bulbous nose called pear-shaped, long and flat filter and low ear implantation. The mos...

Syndromic diarrhea/Tricho-hepato-enteric syndrome (SD/THE) is a rare and severe bowel disorder caused by mutation in SKIV2L or in TTC37, 2 genes encoding subunits of the putative human SKI complex. The estimated prevalence is 1/1,000,000 births and the transmission is autosomal recessive. The classical form is characterized by 5 clinical signs: intractable diarrhea of infancy beginning in the f...

OBJECTIVES Given that tricho-rhino-phalangeal syndrome (TRPS) and pseudohypoparathyroidism/pseudopseudohypoparathyroidism (PHP/PPHP) are very rare monogenic disorders that share some features (distinctive facies, short stature, brachydactyly and, in some patients, intellectual disability) that lead to their misdiagnosis in some cases, our objective was to identify clinical, biochemical or radio...
