© 2019, the author(s). The combined phenotype of thrombocytopenia accompanied by intellectual disability in patients with a de novo heterozygous mutation, i.E., p.Tyr64Cys in CDC42, signifies a clinically recognizable novel syndrome that has been eponymized as “takenouchi-kosaki syndrome” (OMIM #616737).Acoustic neuroma symptoms neck pain in the present study, a detailed phenotypic analysis performed for a total of five patients with takenouchi-kosaki syndrome revealed that intellectual disability, macrothrombocytopenia, camptodactyly, structural brain abnormalities with sensorineural deafness, hypothyroidism, and frequent infections comprise the cardinal features of this condition.Acoustic neuroma symptoms neck pain A morphologic analysis of platelets derived from three affected individuals was performed using electron microscopy. The platelets of the three patients were large and spherical in shape.Acoustic neuroma symptoms neck pain furthermore, platelet α-granules were decreased, while vacuoles were increased. We further performed a functional analysis of p.Tyr64Cys in CDC42 through CRISPR/cas9-mediated gene editing in a caenorhabditis elegans model.Acoustic neuroma symptoms neck pain this functional analysis suggested that the mutant allele has hypomorphic effects. Takenouchi-kosaki syndrome is clinically recognizable by the combined phenotype of intellectual disability, macrothrombocytopenia, camptodactyly, structural brain abnormalities with sensorineural deafness, hypothyroidism, and frequent infections as well as the identification of a heterozygous de novo mutation in CDC42, i.E., p.Tyr64Cys.Acoustic neuroma symptoms neck pain

Chromosome 12q15 microdeletion syndrome is characterized by intellectual disability and dysmorphic facial features, but the associations between each of the deleted genes and the phenotypes of 12q15 microdeletion syndrome remain unclear.Acoustic neuroma symptoms neck pain recently, the smallest region of overlap in 16 previously reported patients was used to define three candidate genes for the 12q15 microdeletion syndrome: CNOT2, KCNMB4, and PTPRB.Acoustic neuroma symptoms neck pain among these three candidate genes, CNOT2 maintains the structural integrity of the carbon catabolite repressor 4 (CCR4)-negative on TATA (NOT) complex, which plays a key role in regulating global gene expression, and is essential for the enzymatic activity of the CCR4-NOT complex.Acoustic neuroma symptoms neck pain disruption of the CCR4-NOT complex results in dysregulation of global gene expression, and is associated with various human disease processes, including neuronal diseases.Acoustic neuroma symptoms neck pain therefore, CNOT2 haploinsufficiency might account for the neurological features of the 12q15 microdeletion syndrome. Herein, we document a 12-year-old female patient with mild intellectual disability and multiple structural abnormalities including cleft lip and palate and 2–3 toe syndactyly.Acoustic neuroma symptoms neck pain she exhibited dysmorphic facial features such as upslanting and short palpebral fissures, micrognathia, low-set ears, and hypoplastic antihelix.Acoustic neuroma symptoms neck pain A microarray analysis showed a de novo 1.32-mb deletion within 12q15 that included CNOT2 and 14 other genes. Remapping of the 12q15 deletion region in the 16 previously reported patients together with that in the newly identified patient indicated that CNOT2 is the only gene that is commonly deleted.Acoustic neuroma symptoms neck pain these findings suggest that CNOT2 is the prime candidate for the neurological phenotypes of the 12q15 microdeletion syndrome.Acoustic neuroma symptoms neck pain

© 2018 wiley periodicals, inc. Schuurs-hoeijmakers syndrome is a rare disease characterized by intellectual disability and dysmorphic facial features among various physical abnormalities due to PACS1 mutation.Acoustic neuroma symptoms neck pain to date, 28 patients with a recurrent de novo PACS1 mutation (c.607C > T) have been reported, primarily in western populations.Acoustic neuroma symptoms neck pain here, we describe two japanese patients with schuurs-hoeijmakers syndrome with a recurrent PACS1 mutation. In addition to the typical clinical symptoms, each patient presented novel clinical phenotypes.Acoustic neuroma symptoms neck pain one patient presented with involuntary movements and was treated with trihexyphenidyl hydrochloride. We hypothesized that the PACS1 mutation leads to an inherent dopaminergic insufficiency that underlies the developing symptoms along with the neurodevelopmental processes.Acoustic neuroma symptoms neck pain the second patient was diagnosed with lipomyelomeningocele during an examination for severe constipation at the age of 2 years and 8 months.Acoustic neuroma symptoms neck pain the diagnosis of lipomyelomeningocele in this patient was delayed due to the lack of cutaneous lesions. As the majority of patients with PACS1 mutation present constipation, underdiagnosis of lipomyelomeningocele is a possibility.Acoustic neuroma symptoms neck pain as the phenotypic expansion of the patients with schuurs-hoeijmakers syndrome was not fully recognized, additional studies are needed to clarify the clinical spectrum.Acoustic neuroma symptoms neck pain

© 2019 wiley periodicals, inc. Cleft palate can be classified as either syndromic or nonsyndromic. SATB2-associated syndrome is one example of a syndromic cleft palate that is accompanied by intellectual disability, and various dental anomalies.Acoustic neuroma symptoms neck pain SATB2-associated syndrome can be caused by several different molecular mechanisms including intragenic mutations and deletions of SATB2.Acoustic neuroma symptoms neck pain here, we report two patients with SATB2 truncating mutations (p.Arg239* and p.Asp702Thrfs*38) and one with a 4.4 megabase deletion including the SATB2 locus.Acoustic neuroma symptoms neck pain all three patients had cleft palate and other dysmorphic features including macrodontia wide diastema. None of the three patients had acquired any meaningful words at the age of 5 years.Acoustic neuroma symptoms neck pain in a review of the linguistic natural history of presently reported three patients and 30 previously reported patients, only two patients had attained verbal skills beyond speaking a few words.Acoustic neuroma symptoms neck pain this degree of delayed speech contrasts with that observed in the prototypic form of syndromic cleft palate, 22q11.2 deletion syndrome.Acoustic neuroma symptoms neck pain the recognition of SATB2-associated syndrome prior to palatoplasty would be important for plastic surgeons and the families of patients because precise diagnosis should provide predictive information regarding the future linguistic and intellectual abilities of the patients.Acoustic neuroma symptoms neck pain macrodontia with a wide diastema and cleft palate is a helpful and highly suggestive sign for the diagnosis of SATB2-associated syndrome.Acoustic neuroma symptoms neck pain

The TWIST family is a group of highly conserved basic helix–loop–helix transcription factors.Acoustic neuroma symptoms neck pain in humans, TWIST1 haploinsufficiency causes saethre–chotzen syndrome, which is characterized by craniosynostosis. Heterozygous localized TWIST1 and TWIST2 basic domain substitutions exert antimorphic effects to cause sweeney–cox syndrome, barber–say syndrome, and ablepharon-macrostomia syndrome, respectively.Acoustic neuroma symptoms neck pain sweeney–cox syndrome, barber–say syndrome, and ablepharon-macrostomia syndrome share the facial features of ablepharon, hypertelorism, underdevelopment of the eyelids, and cheek pads adjacent to the corners of the mouth.Acoustic neuroma symptoms neck pain existence of phenotypic overlap between saethre–chotzen syndrome and sweeney–cox syndrome remains unknown. Herein, we document a male infant with the distinctive facial features of ablepharon, hypertelorism, cheek pads adjacent to the corners of the mouth, and bilateral coronal suture craniosynostosis who had a de novo heterozygous mutation in the basic domain of TWIST1, that is, c.351C>G p.Glu117Asp.Acoustic neuroma symptoms neck pain the pathogenicity of this variant was supported by in silico and in vivo evidence. Our review showed that sweeney–cox syndrome appears to share many characteristics with barber–say syndrome and ablepharon-macrostomia syndrome except for craniosynostosis, which is a cardinal feature of saethre–chotzen syndrome.Acoustic neuroma symptoms neck pain an amino acid substitution from glu117 to asp, both of which are the sole members of negatively charged amino acids, resulted in a prototypic sweeney–cox syndrome phenotype.Acoustic neuroma symptoms neck pain this suggests that any amino acid substitutions at glu117 would likely lead to the sweeney–cox syndrome phenotype or lethality.Acoustic neuroma symptoms neck pain the present observation suggests that a localized TWIST1 basic domain substitution, that is, p.Glu117Asp, in TWIST1 may exert a mild antimorphic effect similar to that of haploinsufficiency, leading to craniosynostosis and ablepharon.Acoustic neuroma symptoms neck pain
