PHACE Syndrome: A Rare Case.

ABSTRACT: PHACE syndrome (OMIM 606519) is a rare neurocutaneous vascular disorder, characterized by posterior fossa malformations, large cervicofacial infantile hemangiomas, arterial anomalies, aortic coarctation, cardiac abnormalities, and eye abnormalities. The long-term outcome of PHACE syndrome patients is unclear; however, it seems that they are at risk for childhood stroke. The radiologist has an important role on diagnosis of PHACE syndrome and in the assessment of potential complications. Investigation of infants with segmental craniofacial hemangiomas should include cranial magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the cerebral and cervical arteries. Brain MRI and MRA findings of a 5-year-old female patient with PHACE syndrome are presented.

A case of phace syndrome and acquired hypopituitarism?

Project description:BACKGROUND:PHACE is a neurocutaneous syndrome associated with: Posterior fossa brain malformations, large "segmental" facial hemangiomas, arterial cerebrovascular-, cardiovascular-, and eye anomalies. CASE VIGNETTE:We are reporting a girl with PHACE syndrome. The patient had a congenital right-sided facial hemangioma with plaque-morphology. At age 11?years and 2?months she presented with short stature, markedly decreased growth velocity and signs and symptoms suggestive of hypothyroidism. Magnetic Resonance Imaging (MRI) of the brain revealed complex structural and cerebrovascular arterial anomalies, including an empty sella. Testing of pituitary function revealed multiple pituitary dysfunctions, including absolute growth hormone deficiency, hypogonadotropic hypogonadism, central hypothyroidism, and secondary adrenal insufficiency. CONCLUSIONS:This case suggests the necessity to screen all patients with PHACE syndrome and intracranial malformations for pituitary dysfunction at regular intervals.

Candidate locus analysis for PHACE syndrome.

Project description:PHACE syndrome (OMIM #606519) is a neurocutaneous syndrome of unknown etiology and pathogenesis. We report on an individual with PHACE syndrome with a complete deletion of SLC35B4 on 7q33. In order to further analyze this region, SLC35B4 was sequenced for 33 individuals with PHACE syndrome and one parental set. Common polymorphisms with a possible haplotype but no disease causing mutation were identified. Sixteen of 33 samples of the PHACE syndrome patients were also analyzed for copy number variations using high-resolution oligo-comparative genomic hybridization (CGH) microarray. A second individual in this cohort had a 26.5 kb deletion approximately 80 kb upstream of SLC35B4 with partial deletion of the AKR1B1 on 7q33. The deletions observed on 7q33 are not likely the singular cause of PHACE syndrome; however, it is possible that this region provides a genetic susceptibility to phenotypic expression with other confounding genetic or environmental factors.

Prevalence and Clinical Characteristics of Headaches in PHACE Syndrome.

Project description:PHACE (posterior fossa brain malformation, hemangiomas, arterial anomalies, coarctation of the aorta and cardiac defects, and eye abnormalities) syndrome is a neurocutaneous disorder often involving the cerebral vasculature. PHACE patients appear to have early-onset and severe headaches more commonly than children without PHACE. The objective of this study was to characterize the clinical features and prevalence of headache by conducting a cross-sectional survey of families in 2 large PHACE registries. Sixty-six percent of eligible families completed the survey in which 62.7% of respondents reported headaches. Average age of headache onset was 48.8 months. Females were more likely to have headaches (68.6% vs 30.8%, P = .014). Families reported associated migrainous features including nausea (62.5%), vomiting (37.5%), photophobia (75%), and phonophobia (75%). Headaches occurred at least weekly in 29.4%, lasted ≥1 hour in 85.4%, and led to ≥1 hospital admission in 15.7%. Three respondents with headaches had at least 1 ischemic stroke. We demonstrated that headaches are common among PHACE patients, develop at an early age, and have migrainous features.

X Chromosome-Inactivation Patterns in 31 Individuals with PHACE Syndrome.

Project description:Segmental hemangiomas of the head and neck can be associated with multiple congenital anomalies in the disorder known as PHACE syndrome (OMIM 606519) (posterior fossa malformations, hemangioma, arterial anomalies, cardiac defects, and eye anomalies). All reported cases of PHACE syndrome to date have been sporadic, and the genetic basis of this disorder has not yet been established. PHACE syndrome has a striking female predominance which has raised the question of X-linked inheritance. In this study, the X chromosome-inactivation (XCI) patterns of 31 females with PHACE syndrome and their mothers were analyzed using blood-derived DNA and X-chromosome locus methylation assay. This study was performed to test the hypothesis that some cases of PHACE syndrome are due to X-linked inheritance and favorable skewing in the mothers may protect against a severe phenotype, but the clinical phenotype may be unmasked in daughters with a random pattern of X-inactivation. XCI analysis was informative in 27/31 mothers. Our results identified skewed XCI in 5 of 27 (19%) informative mothers, which is not statistically significant with a p value of 0.41. None of the mothers reported significant medical problems, although a full PHACE work-up has not been performed in these individuals. Skewed XCI in the mothers of children with PHACE was identified in only a minority of cases. Based on these results, genetic heterogeneity is likely in PHACE syndrome, although it is possible a subset of cases are caused by a mutation in an X-linked gene.

Copy number variation analysis in 98 individuals with PHACE syndrome.

Project description:PHACE syndrome is the association of large segmental facial hemangiomas and congenital anomalies, such as posterior fossa malformations, cerebral arterial anomalies, coarctation of the aorta, eye anomalies, and sternal defects. To date, the reported cases of PHACE syndrome have been sporadic, suggesting that PHACE may have a complex pathogenesis. We report here genomic copy number variation (CNV) analysis of 98 individuals with PHACE syndrome as a first step in deciphering a potential genetic basis of PHACE syndrome. A total of 3,772 CNVs (2,507 duplications and 1,265 deletions) were detected in 98 individuals with PHACE syndrome. CNVs were then eliminated if they failed to meet established criteria for quality, spanned centromeres, or did not contain genes. CNVs were defined as "rare" if not documented in the database of genomic variants. Ten rare CNVs were discovered (size range: 134-406 ?kb), located at 1q32.1, 1q43, 3q26.32-3q26.33, 3p11.1, 7q33, 10q24.32, 12q24.13, 17q11.2, 18p11.31, and Xq28. There were no rare CNV events that occurred in more than one subject. Therefore, further study is needed to determine the significance of these CNVs in the pathogenesis of PHACE syndrome.

PHACE syndrome with lip haemangioma, microphthalmos and persistent fetal vasculature.

Project description:An 11-month-old baby girl presented with white reflex in her left eye. On examination, there was a 6.5×5 mm(2)haemangioma present over her face involving on her lower lip. Systemic examinations were within normal limits. The left eye was small, with an axial length of 16.08 mm and had a cataract. Ultrasonography of the left eye was suggestive of the presence of a vascular stalk, persistent hyperplasia of a primary vitreous, or persistent fetal vasculature with vitreous haemorrhage. On MRI, the left eye was small with vitreous haemorrhage. Left eye lens aspiration was performed and the bleeding vascular stalk behind the lens was cauterised with diathermy. The right eye was normal. The patient was diagnosed as having PHACE syndrome (Posterior fossa malformations, Hemangiomas, Arterial anomalies, Coarctation of the aorta and other cardiac defects, and Eye abnormalities syndrome). On follow-up, she was able to follow light with her left eye.

Nance-Horan Syndrome: A Rare Case Report.

Project description:Dentofacial anomalies may guide us to the diagnosis of many congenital and hereditary syndromes. A 9-year-old boy was diagnosed with Nance-Horan syndrome. This syndrome is an extremely rare X-linked genetic disorder which is entirely expressed in males with semi-dominant transmission which results from mutations occurring in male gametes. It is characterized by facial dysmorphism such as long face, prominent nose and mandibular prognathism, ocular abnormalities such as congenital cataract, microcornea, microphthalmia and strabismus, and dental anomalies including mulberry molars and screwdriver-shaped incisors. Heterozygous females inherit this disease and also suffer from this syndrome but in a milder form. Approximately one-third of the affected males show signs of developmental delay and intellectual abnormalities. This syndrome is very rare and the incidence of the disease has not been established so far. The present article describes the clinical and radiological features and the genetic implications of this syndrome.
