MOTA syndrome, the acronym for Manitoba-oculo-tricho-anal syndrome (OMIM 248450), is a distinct autosomal recessive multiple malformation syndrome caused by mutations in the FREM1 gene (OMIM 608944). Eight patients with MOTA syndrome and a pathogenic FREM1 mutation have previously been documented. We report on a new male patient, 3.5 months old, with MOTA syndrome, who presented with the follow...
Known vertebrate GATA proteins contain two zinc fingers and are required in development, whereas invertebrates express a class of essential proteins containing one GATA-type zinc finger. We isolated the gene encoding TRPS1, a vertebrate protein with a single GATA-type zinc finger. TRPS1 is highly conserved between Xenopus and mammals, and the human gene is implicated in dominantly inherited tri...
Mutation of distal-less homeobox 3 (DLX3) is responsible for human tricho-dento-osseous syndrome (TDO) with amelogenesis imperfecta, indicating a crucial role of DLX3 in amelogenesis. However, the expression pattern of DLX3 and its specific function in amelogenesis remain largely unknown. The aim of this study was to investigate the effects of DLX3 on enamel matrix protein (EMP) genes. By immun...
Tricho-rhino-phalangeal syndrome (TRPS) is an autosomal dominant craniofacial and skeletal dysplasia that is caused by mutations involving the TRPS1 gene. Patients with TRPS have short stature, hip abnormalities, cone-shaped epiphyses and premature closure of growth plates reflecting defects in endochondral ossification. The TRPS1 gene encodes for the transcription factor TRPS1 that has been de...
Syndromic diarrhea/tricho-hepato-enteric syndrome (SD/THE) is a rare disease linked to the loss of function of either TTC37 or SKIV2L, two components of the SKI complex. It is characterized by a combination of 9 signs (intractable diarrhea, hair abnormalities, facial dysmorphism, immune abnormalities, IUGR/SGA, liver abnormalities, skin abnormalities, congenital heart defect and platelet abnorm...
The homeodomain protein Distal-less-3 (Dlx3) plays a crucial role during embryonic development. This transcription factor is known to be essential for placental formation and to be involved in skin and skeletal organogenesis. In humans, a frameshift mutation in the coding sequence of the DLX3 gene results in an ectodermal dysplasia called Tricho-Dento-Osseous syndrome (TDO). The main features o...
Tricho-rhino-phalangeal syndrome (TRPS) is a heritable congenital syndrome characterized by craniofacial and skeletal abnormalities. TRPS is an autosomal dominant syndrome with high penetrance and wide phenotypic variability. TRPS is classified into three subtypes; TRPS types I (TRPS I; OMIM 190350) and III (TRPS III; OMIM 190351) have distinct clinical manifestations that often correspond to d...
The RNA exosome has a key role in RNA decays and RNA quality control. In 2012, two human Mendelian diseases: syndromic diarrhea/tricho-hepato-enteric syndrome (SD/THE) and Ponto-cerebellar hypoplasia type 1(PCH1) were linked to the RNA exosome or its cofactor's defect. SD/THE's main features are an intractable diarrhea of infancy associated with hair abnormalities, facial dysmorphism, intra ute...
BACKGROUND Manitoba-oculo-tricho-anal (MOTA) syndrome is a rare condition defined by eyelid colobomas, cryptophthalmos and anophthalmia/microphthalmia, an aberrant hairline, a bifid or broad nasal tip, and gastrointestinal anomalies such as omphalocele and anal stenosis. Autosomal recessive inheritance had been assumed because of consanguinity in the Oji-Cre population of Manitoba and reports o...
The homeodomain transcription factor distal-less homeobox 3 gene (DLX3) is required for hair, tooth and skeletal development. DLX3 mutations have been found to be responsible for Tricho-Dento-Osseous (TDO) syndrome, characterized by kinky hair, thin-pitted enamel and increased bone density. Here we show that the DLX3 mutation (c.533 A>G; Q178R) attenuates osteogenic potential and senescence of ...
