Animal models resembling human mutations are valuable tools to research the features of complex human craniofacial syndromes. This is the first report on a viable dominant mouse model carrying a non-synonymous sequence variation within the endothelin receptor type A gene (Ednra c.386A>T, p.Tyr129Phe) derived by an ENU mutagenesis program. The identical amino acid substitution was reported recently as disease causing in three individuals with the mandibulofacial dysostosis with alopecia (MFDA, OMIM 616367) syndrome...

Microtia is a congenital defect affecting external ears, which appear smaller and sometimes malformed. Here we describe a five-generation family with isolated bilateral microtia segregating as an autosomal dominant trait. Similar features had been previously observed in an autosomal dominant family with non-syndromic microtia and hearing loss segregating with a HOXA2 nonsense variant. HOXA2 biallelic mutations were also described in an inbreed family with autosomal recessive microtia, hearing impairment and incomplete cleft palate...

OBJECTIVE: To determine the factors contributing towards hearing impairment in patients with cleft lip/palate. METHOD: A prospective analysis was conducted on 173 patients (346 ears) with cleft lip and palate (CL/P) who presented to the combined cleft clinic at University Malaya Medical Centre (UMMC) over 12 months. The patients' hearing status was determined using otoacoustic emission (OAE), pure tone audiometry (PTA) and auditory brainstem response (ABR). These results were analysed against several parameters, which included age, gender, race, types of cleft pathology, impact and timing of repair surgery...

Stickler syndrome is an inherited connective tissue disorder that affects the eyes, cartilage and articular tissues. The phenotypes of Stickler syndrome include congenital high myopia, retinal detachment, premature joint degeneration, hearing impairment and craniofacial anomalies, such as cleft palate and midline facial hypoplasia. The disease is genetically heterogeneous, and the majority of the cases are caused by mutations in the COL2A1 gene. We examined 40 Japanese patients with Stickler syndrome from 23 families to determine whether they had mutations in the COL2A1 gene...

BACKGROUND: The major drawbacks of standard procedures of palatoplasty have been inadequate palatal lengthening, velopharyngeal incompetence, impaired maxillary growth with mid-face retrusion and high fistula rates. The Furlow's double opposing Z-plasty is accepted as one of the better procedures for treating cleft palates. METHODS: This paper compared Furlow's procedure to Veau Kilner Wardill's procedure performed on 63 patients from July 2000 till February 2005...

Interstitialdeletions of chromosome band 10q22.1q22.3 are rare. We here report a 2.5-year-old female patient with developmental delay, speech delay, congenital cleft palate, and bilateral hearing impairment. The girl's karyotype was normal. Chromosome microarray analysis (CMA) revealed a 1.77-Mb de novo interstitial deletion in 10q22.2q22.3. The deletion harbors 9 genes, including KAT6B, DUPD1, DUSP13, SAMD8, VDAC2, COMTD1, ZNF503, NCRNA00245, and C10orf11. This is the first patient with a deletion of the smallest size in 10q22...

Isolated gonadotropin-releasing hormone (GnRH) deficiency (IGD) pertains to a group of genetic disorders consisting of anosmic hypogonadotropic hypogonadism (Kallmann syndrome, KS) and normosmic idiopathic hypogonadotropic hypogonadism (nIHH). KS is genetically heterogeneous. We hereby present 5 young male patients with GnRH deficiency caused by mutations in the KAL1 gene. Their ages ranged from 9 months to 16 years. They were referred to our department for an endocrine consultation for micropenis. Hormone assays showed low circulating gonadotropins and testosterone...

OBJECTIVE: Cleft lip and palate (CLP) is comprised within the wide range of congenital deformities of the maxillofacial region with an overall incidence on the increase from 1:1000 to 1:700 live births thus being the most common congenital birth error. Failure of the lateral and medial nasal processes to fuse with the anterior extension of maxillary processes and of the palatal shelves between the 4th and 8th gestational week results in cleft lip and palate. Clefts include different types with variable severity, confirming the complexity and unpredictable expression of cleft modality and have a multifactorial aetiology...

BACKGROUND: Deletions of the long arm of chromosome X in males are a rare cause of X-linked intellectual disability. Here we describe a patient with an interstitial deletion of the Xq21.1 chromosome. CASE PRESENTATION: In a 15 year boy, showing intellectual disability, short stature, hearing loss and dysmorphic facial features, a deletion at Xq21.1 was identified by array-CGH. This maternally inherited 5.8 Mb rearrangement encompasses 14 genes, including BRWD3 (involved in X-linked intellectual disability), TBX22 (a gene whose alterations have been related to the presence of cleft palate), POU3F4 (mutated in X-linked deafness) and ITM2A (a gene involved in cartilage development)...

BACKGROUND: Cleft lip and palate are among the most common congenital malformations, with an incidence of around 1 in 700. Cleft palate (CP) results in impaired Eustachian tube function, and 90% of children with CP have otitis media with effusion (OME) histories. There are several approaches to management, including watchful waiting, the provision of hearing aids (HAs) and the insertion of ventilation tubes (VTs). However, the evidence underpinning these strategies is unclear and there is a need to determine which treatment is the most appropriate...

Providing clinically relevant prognoses and treatment information for people with a chromsome18q deletion is particularly challenging because every unrelated person has a unique region of hemizygosity. The hemizygous region can involve almost any region of 18q including between 1 and 101 genes (30 Mb of DNA). Most individuals have terminal deletions, but in our cohort of over 350 individuals 23% have interstitial deletions. Because of this heterogeneity, we take a gene by gene approach to understanding the clinical consequences...

UNLABELLED: Cleft palate only (CPO) is a common congenital malformation, and most patients are diagnosed within the first weeks after birth. Late diagnosis of the cleft palate (CP) could initially result in feeding and growth impairment, and subsequently speech and hearing problems later in life. The purpose of this study is to retrospectively investigate (1) at which age CPO is diagnosed and (2) how the presence of syndromes and other factors relate to the age at diagnosis. The mean age of all children at our centre with CPO included between 1997 and 2014 at diagnosis (n = 271) was 1 year and 4 months...

Kabuki or Niikawa-Kuroki syndrome (KS) is a rare disorder with multiple malformations and recurrent infections, especially otitis media. This study aimed to investigate the genetic defects in Kabuki syndrome and determine if immune status is related to recurrent otitis media. Fourteen patients from 12 unrelated families were enrolled in the 9-year study period (2005-2013). All had Kabuki faces, cleft palate, developmental delay, mental retardation, and the short fifth finger. Recurrent otitis media (12/14) and hearing impairment (8/14) were also more common features...
