Elsten EECM, Caron CJJM, Dunaway DJ, Padwa BL, Forrest C, Koudstaal MJ. Dental anomalies in craniofacial microsomia: A systematic review. Orthod Craniofac Res 2019; 23:16-26. [PMID: 31608577 PMCID: PMC7003932 DOI: 10.1111/ocr.12351] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2019] [Revised: 10/08/2019] [Accepted: 10/08/2019] [Indexed: 12/12/2022]
Abstract
Objective: To provide an overview on the prevalence and types of dental anomalies in patients with craniofacial microsomia (CFM). Eligibility criteria: Inclusion criteria were CFM and dental anomalies. The following data were extracted: number of patients, methodology, mean age, sex, affected side, severity of mandibular hypoplasia, dentition stage and dental anomalies. Information sources: Cochrane, EMBASE, PubMed, MEDLINE Ovid, Web of Science, CINAHL EBSCOhost and Google Scholar, searched until the 30 August 2019. Risk of bias: The quality was examined with the OCEBM Levels of Evidence. Included studies: In total, 13 papers were included: four retrospective cohort studies, four prospective cohort studies, four case‐control studies and one case series. Synthesis of results: The studies reported information on dental agenesis, delayed dental development, tooth size anomalies, tooth morphology and other dental anomalies. Description of the effect: Dental anomalies are more often diagnosed in patients with CFM than in healthy controls and occur more often on the affected than on the non‐affected side. Strengths and limitations of evidence: This is the first systematic review study on dental anomalies in CFM. However, most articles were of low quality. Interpretation: Dental anomalies are common in CFM, which might be linked to the development of CFM. The pathophysiology of CFM is not entirely clear, and further research is needed.

Interstitial 14q24.3 to q31.3 deletion in a 6-year-old boy with a non-specific dysmorphic phenotype. Mol Cytogenet 2014; 7:77.

Abstract
BACKGROUND Few patients with interstitial deletions in the distal long arm of chromosome 14 have been reported, and these patients showed rather indistinct features, including growth and mental retardation and phenotypic alterations. RESULTS We describe a de novo 14q interstitial deletion in a 6-year-old boy with dysmorphic facial traits such as hypertelorism, short and narrow palpebral fissures, broad nose with anteverted nostrils, long philtrum, thin upper lip with cupid's bow, prominent and everted lower lip, mildly low-set ears, as well as moderate developmental delay and mild mental retardation. Array-CGH mapped the deletion to the region 14q24.3 to 14q31.3, including 13.11 Mb, proximal to the imprinted genomic region of 14q32. CONCLUSION This mild phenotypic presentation suggests that the deleted segment does not contain essential genes for early organ development. Twenty-two genes with known functions, including Neurexin III (NRXN3, OMIM 600567), map to the region deleted in the propositus.

Abstract
Leukodystrophy with vanishing white matter (VWM) is a neurodegenerative disorder with autosomal recessive traits that is caused by alteration of the eukaryotic translation initiation factor-2B (EIF2B). An 11-month-old patient with distinctive features began to exhibit progressive developmental deterioration associated with intractable epilepsy, which was triggered by recurrent acute infectious diseases. Brain magnetic resonance imaging (MRI) revealed abnormal white matter intensity. Chromosomal microarray testing identified a submicroscopic deletion at 14q24.3 that included EIF2B2, the gene encoding one of the subunits of EIF2B. Because the patient's clinical findings were distinctive for VWM, compound heterozygous mutations of EIF2B2 were suspected, and subsequent sequencing analysis of the remaining allele unmasked the existence of a novel missense mutation of EIF2B2 (V85W). Some distinctive features including small palpebral fissures, bushy eyebrows, ear abnormalities, small upturned nose, downturned corners of the mouth, and micrognathia may be the common features of the patients with 14q24.3 deletions.

Abstract
Distal interstitial deletions of chromosome 14 involving the 14q24-q23.2 region are rare, and only been reported so far in 20 patients. Ten of these patients were analyzed both clinically and genetically. Here we present a de novo interstitial deletion of chromosome 14q24.3-q32.2 in a male patient with developmental delay, language impairment, plagiocephaly, BPES features (blepharophimosis, ptosis, epicanthus), and congenital heart defect. The deletion breakpoints were fine mapped using fluorescence in situ hybridization (FISH) and the size of the deletion is estimated to be approximately 23 Mb. Based on genotype-phenotype comparisons of the 10 previously published patients and the present case, we suggest that the shortest regions for deletion overlap may include candidate genes for speech impairment, mental retardation, and hypotonia.

Abstract
Interstitial deletions of the long arm of chromosome 14 are relatively rare. We report a 8.5-year-old girl with dysmorphic facial features and mental retardation associated with a de novo interstitial deletion of chromosome 14. The comparison between our patient and all published patients is reviewed. The genetic investigations have allowed us to define the critical chromosomal region and to start an accurate follow-up.

Abstract
Interstitial deletions of 14q including band 14q31 are uncommon. We report on a 3 year-old Tunisian girl who had a de novo interstitial deletion of the long arm of chromosome 14. The molecular cytogenetic study has identified the deletion as a del(14)(q24.3q32.2) covering nearly 24Mb. This abnormality was associated to phenotypic manifestations, mainly peculiar face, developmental delay and hypoplastic corpus callosum.

Abstract
Holt-Oram syndrome, the major "heart-hand" syndrome is defined by the association of radial defects or triphalangeal thumbs and septal heart defects. The transmission is autosomal dominant and the causative gene has been shown to be TBX5, located on 12q24.1, which encodes a transcription factor. Genetic heterogeneity has been suggested by several reports. We identified a 14(q23.3 approximately 24.2q31.1) deletion in a boy presenting severe bilateral asymmetrical radial aplasia, congenital heart defects, and developmental delay. This deletion, whose size could be estimated to be 9.6-13.7 Mb, was shown to be inherited via his mother's interchromosomal insertion. This is the second report of a chromosome 14 interstitial deletion associated with clinical features of Holt-Oram syndrome. These observations suggest the existence of a new "heart-hand" locus on chromosome 14q.

Abstract
A patient with hypotonia, blepharophimosis, ptosis, a bulbous nose, a long philtrum, upturned corners of the mouth, and mild developmental delay was found to have a small subtelomeric deletion of the long arm of chromosome 14 (q32.31-qter). In comparing her phenotype with previously reported patients with similar 14q deletions, due to either a linear deletion or to a ring chromosome 14, a clinically recognizable terminal 14q microdeletion syndrome was evident. Due to the limited number of cases reported, it was not possible to assign specific features to specific regions of terminal 14q. The comparison of features in cases with a linear deletion of 14qter (n = 19) to those in cases with a deletion due to a ring chromosome 14 (n = 23), both with the same breakpoint in 14q, showed that seizures and retinitis pigmentosa have been found only in patients with ring chromosomes. Several hypotheses are put forward to explain this difference: mitotic instability of ring chromosomes; a telomere position effect in ring chromosomes in which the 14p telomere silences nearby gene(s) on the q-arm; and dose-dependent gene(s) involved in seizures and retinitis pigmentosa located on the short arm of chromosome 14. In our opinion, only seizures may be explained by the mitotic instability of ring chromosomes, while both seizures and retinitis pigmentosa may be explained by silencing of gene(s) on 14q by the 14p telomere; the third hypothesis seems unlikely to explain either symptom.

Abstract
Over the past few years, regions of genomic imprinting have been identified on a small number of chromosomes through a search for the etiology of various disorders. Distinct phenotypes have been associated with both maternal and paternal uniparental disomy (UPD) for chromosome 14. This observation indicates that there are imprinted genes present on chromosome 14, although none have been identified to date. In order to focus the search for imprinted genes on chromosome 14, we analyzed cases of maternal and paternal UPD 14 and compared them with cases of chromosome 14 deletions. Cases of paternal UPD were compared with maternal deletions and maternal UPD compared with paternal deletions. The paternal UPD anomalies seen in maternal deletion cases allowed us to associate the following features and chromosomal regions: Hirsute forehead: del(14)(q12q13. 3) and del(14)(q32); blepharophimosis: del(14)(q32); small thorax: del(14)(q11.2q13); and joint contractures: del(14)(q11.2q13) and del(14)(q31). Comparison of maternal UPD and paternal deletion cases revealed fleshy nasal tip to be most often associated with del(14)(q32), scoliosis with del(14) (q23q24.2), and del(14)(q32. 11qter) and small size at birth to be associated with del(14)(q11q13) and del(14)(q32). Our study, in conjunction with a prior study of UPD 14 and partial trisomy 14 cases, and what is known of imprinting in regions of mouse chromosomes homologous to human chromosome 14, leads us to conclude that 14q23-q32 is likely an area where imprinted genes may reside.

Abstract
A Japanese boy with interstitial deletion of the long arm of chromosome 14, including band 14q31, is described. The characteristic dysmorphic facial features, such as dolichocephaly, bushy eyebrows, horizontal narrow palpebral fissures, long philtrum, etc, and mental and motor developmental delay were observed. Other characteristic clinical manifestations were anuresis and status nonepileptic myoclonia The finding of delayed myelination of the cerebral white matter was observed on magnetic resonance examination, suggesting that an unknown factor related to myelination in the central nervous system might be localized in band 14q31.

Abstract
Two patients and one three generation family with interstitial deletions of distal chromosome band 14q31 are described. The deletions were initially identified by chromosome analysis; we have used highly informative simple sequence repeat polymorphisms to define the deletions at the molecular level. This analysis also establishes the parental origin of the deleted chromosome. One of the patients was initially described as having a terminal deletion of chromosome 14 from 14q31 to 14qter; we show here that this child has instead an interstitial deletion of band 14q31. The smallest deletion involves a single anonymous DNA marker and is associated with an almost normal phenotype. The two patients with larger deletions have phenotypes similar to those seen in previously described cases of interstitial deletions of chromosome 14, including minor dysmorphic features and developmental delay. Delineation of these deletions allows the ordering of markers within the 14q31 region, in which the gene for the degenerative neurological disorder Machado-Joseph disease is localised.

Abstract
We report on 2 unrelated patients who had chromosome analysis performed because of psychomotor delay, failure to thrive, and minor anomalies. Each patient had a novel proximal 14q deletion (q11.2 to q21.1 in patient 737 and q12 to q22 in patient 777). Polymorphic (C-A)n microsatellite markers distributed along the length of chromosome 14q were examined in both patients and their parents in order to determine which marker loci were deleted. The deletion in patient 737 was found to be paternal in origin, based on the analysis of 2 marker loci (D14S54 and D14S70), thus assigning these loci to the deleted interval q11.2 q21.1. Furthermore, 3 loci were not deleted (TCRD, D14S50, and D14S80), suggesting that they are within or proximal to 14q11.2. In the other family (patient 777), none of the markers were fully informative, but the deleted chromosome was determined to be paternally derived based on cytogenetic heteromorphisms. Despite having overlapping proximal 14q deletions, these 2 patients shared few phenotypic similarities except for failure to thrive, micrognathia, and hypoplasia of the corpus callosum. Therefore, a distinct proximal 14q deletion syndrome is not yet apparent. However, the molecular analyses facilitated the localization of several 14q DNA markers to the deletion regions in these 2 patients, while excluding other markers from each deletion.
