cleft palate and learning disability

McKusick-Kaufman syndrome (MKS) is an autosomal recessive multiple malformation syndrome characterized by hydrometrocolpos (HMC) and postaxial polydactyly (PAP). We report a case of a female child with MKS who was transferred to the neonatal intensive care unit of Seoul National University Children's Hospital on her 15th day of life for further evaluation and management of an abdominal cystic mass. She underwent abdominal sonography, magnetic resonance imaging, genitography and cystoscopy which confirmed HMC with a transverse vaginal septum...

PURPOSE: This study explores the importance of production frequency during speech therapy to determine whether more practice of speech targets leads to increased performance within a treatment session, as well as to motor learning, in the form of generalization to untrained words. METHOD: Two children with childhood apraxia of speech were treated with an alternating treatment AB design, with production frequency differing in the 2 treatments. The higher production frequency treatment required 100+ productions in 15 min, while the moderate-frequency treatment required 30-40 productions in the same time period...

We reported on 16 new Brazilian patients and review findings in 12 previously reported cases (25 apparently unrelated Brazilian families) from Hospital of Rehabilitation of Craniofacial Anomalies, presenting with Richieri-Costa-Pereira syndrome. All patients display a unique pattern of anomalies consisting of microstomia, micrognathia, abnormal fusion of mandible, cleft palate/Robin sequence, absence of central lower incisors, minor ears anomalies, hypoplastic first ray, abnormal tibiae, hypoplastic halluces, and clubfeet...

3MC syndrome has been proposed as a unifying term encompassing the overlapping Carnevale, Mingarelli, Malpuech and Michels syndromes. These rare autosomal recessive disorders exhibit a spectrum of developmental features, including characteristic facial dysmorphism, cleft lip and/or palate, craniosynostosis, learning disability and genital, limb and vesicorenal anomalies. Here we studied 11 families with 3MC syndrome and identified two mutated genes, COLEC11 and MASP1, both of which encode proteins in the lectin complement pathway (collectin kidney 1 (CL-K1) and MASP-1 and MASP-3, respectively)...

Osteopathia striata with cranial sclerosis (OMIM ##300373) is an X-linked dominant sclerosing bone dysplasia that presents in females with macrocephaly, cleft palate, mild learning disabilities, sclerosis of the long bones and skull, and longitudinal striations visible on radiographs of the long bones, pelvis, and scapulae. In males this entity is usually associated with foetal or neonatal lethality, because of severe heart defects and/or gastrointestinal malformations, and is often accompanied by bilateral fibula aplasia...

OBJECTIVE: To test the hypothesis that children with orofacial clefts score lower than controls on measures of language and reading and to examine predictors of these outcomes. DESIGN: Longitudinal study tracking the development of children with and without orofacial clefts from infancy through age 7 years. SUBJECTS: Children with isolated cleft lip and palate (n = 29) and cleft palate only (n = 28) were recruited from the craniofacial program in an urban medical center...

Emanuel syndrome is characterized by multiple congenital anomalies and developmental disability. It is caused by the presence of a supernumerary derivative chromosome that contains material from chromosomes 11 and 22. The origin of this imbalance is 3:1 malsegregation of a parental balanced translocation between chromosomes 11 and 22, which is the most common recurrent reciprocal translocation in humans. Little has been published on the clinical features of this syndrome since the 1980s and information on natural history is limited...

We report a 4.5 Mb deletion of 2q33.1 in an individual with developmental delay and cleft palate. There have been various previous reports of deletions of 2q3, all with varying breakpoints and all larger than the current case. Whilst there is some variation in the phenotypes of patients with 2q3 deletions all share a commonly deleted region within 2q33.1 which includes SATB2, a gene previously shown to be associated with cleft palate. The phenotypic features of our patient are milder than those reported so far...

Rare copy number variants (CNVs) are frequently associated with common neurological disorders such as mental retardation (MR; learning disability), autism, and schizophrenia. CNV screening in clinical practice is limited because pathological CNVs cannot be distinguished routinely from benign CNVs, and because genes underlying patients' phenotypes remain largely unknown. Here, we present a novel, statistically robust approach that forges links between 148 MR-associated CNVs and phenotypes from approximately 5,000 mouse gene knockout experiments...

INTRODUCTION: Chromosome 22q11 microdeletion syndrome, DiGeorge syndrome or CATCH 22 spectrum, is characterised by conotruncal heart malformations, facial dysmorphisms, cleft palate, velopharyngeal insufficiency, transient hypocalcemia and T cell disorders. Furthermore, a significant number of patients may present autism-type developmental disorders, learning disabilities, attention deficit hyperactivity disorder or schizophrenia-like psychiatric problems. CASE REPORT: A girl with congenital heart disease that had been treated surgically in the neonatal period, who presented psychomotor retardation, dysmorphic features and microcephaly...

We report the clinical and genetic evaluation of a 2-year-old Greek female with striking phenotypic similarities to the three previously published cases of Okamoto syndrome. The main features were characteristic facies, cleft palate, generalized hypotonia, severe developmental delay, congenital hydronephrosis, and congenital heart defects. Routine chromosome testing and whole-genome high-resolution comparative genetic hybridization analysis were negative for any gross numerical or structural chromosome aberrations and for microdeletions/duplications of more than 3 million base pairs respectively...

BACKGROUND: Patients with palatal clefts are predisposed to developing speech and language abnormalities. Emerging evidence indicates that children with cleft lip and/or cleft palate have higher rates of learning disabilities than the general population and differences in brain morphology. METHODS: Magnetic resonance imaging of 12 individuals with isolated unilateral complete clefts of the lip and palate produced functional images during three lexical processing tasks: generation of verbs, opposites, and rhymes...

We report on a detailed phenotypic characterization of two patients with novel de novo deletions involving 15q13q14, a chromosomal region immediately distal to the Prader-Willi/Angelman syndrome critical interval. Both cases were detected by the clinical array-based comparative genomic hybridization (array-CGH) and were precisely delineated through the high-density Agilent 244 K oligonucleotide array. The comparison of our patients with previously reported deletion cases involving the 15q13q14 region demonstrated a recurrent pattern of developmental anomalies including mild dysmorphic features, cleft palate/bifid uvula, congenital heart defects (PFO or ASD), developmental delay, and learning disabilities...

BACKGROUND: Chromosome 22q11.2 microdeletion syndrome (22q11DS) is characterized by cleft palate, cardiac anomalies, characteristic facies, high prevalence of skeletal anomalies and learning disability. OBJECTIVE: To evaluate the prevalence of craniovertebral junction anomalies in children with 22q11DS and compare these findings to those in nonsyndromic children with velopharyngeal insufficiency (VPI). MATERIALS AND METHODS: Sequential CT scans performed for presurgical carotid assessment in 76 children (45 children positive for chromosome 22q11...

This study investigated the experience of receiving a diagnosis of clefting in the prenatal or postnatal period. Open-ended interviews were conducted with 20 parents of children with cleft lip with or without cleft palate. Interviews were transcribed and analyzed using a qualitative descriptive approach with an emphasis on thematic analysis. Common themes emerged from participants' responses regarding the delivery of the diagnosis, preparation for the birth of their child, advantages and disadvantages of prenatal diagnosis, use of the Internet, views on abortion and genetic testing, among other issues...

Velocardiofacial syndrome (VCFS, or Shprintzen syndrome) is the most common syndrome associated with palatal anomalies and is characterized by the following major features: cleft palate, cardiac anomalies, typical facies, and learning disabilities. Ophthalmologic abnormalities are seen in 70% of cases and include posterior embryotoxon, bilateral cataracts, tortuous retinal vessels, and small optic disks. Congenital absence of the nasolacrimal duct is a rare condition with only a few cases reported, most of which describe complete bony occlusion at the distal end of the lacrimal sac...

Although several reports have described the co-occurrence of autism in subjects with chromosome 22 abnormalities including trisomy 22, translocation 20/22, 22q11.2 deletion, ring chromosome 22, and 22q13.3 deletion, there is no report with 22q11.2 duplication. We report a 9-year-old girl, referred to our department for her behavioural problems and language delay. She was diagnosed with autistic disorder according to DSM-IV criteria. Because of her dysmorphic characteristics comprising narrow face, narrow forehead, mandibular prognathism, synophrys, and operated cleft palate and cardiac problems, she had gone under cytogenetic analysis...

OBJECTIVE: Prenatal alcohol exposure affects 1 in 100 births in the United States and results in craniofacial dysmorphologic condition and learning disabilities. In a model for fetal alcohol syndrome, neuroprotective peptides prevented fetal death and learning deficits. The gamma-aminobutyric acid A (GABA) receptor subunit GABAbeta3 plays a critical role for nervous system and palate development. Our objective was to determine whether the neuropeptides prevented alcohol-induced damage through GABAbeta3...

Shprintzen syndrome (velo-cardio-facial, VCFS) is a very rare morbid entity, seen in either familial or sporadic forms, with major clinical findings such as facial dysmorphism, cleft palate, cardiovascular (especially conotruncal-anomalies), mild/moderate mental retardation, or, more commonly, observed learning difficulty. Tendency to behavioral disorders and bipolar schizophrenic diseases may be present in these cases. Autosomal dominant inheritance has been reported. VCFS appears as a consequence of microdeletion in the 22q11 chromosomal band...
