OBJECTIVE Feeding difficulties are reported widely in infants with cleft lip and/ or palate. There is, however, a paucity of objective information about the feeding patterns of these infants. This study compared patterns of feeding in infants with unrepaired cleft lip and palate with healthy noncleft infants of a similar age. SETTING North Thames Regional Cleft Centre. The noncleft cohort was...
BACKGROUND Tetralogy of Fallot (TOF) is the commonest cyanotic form of congenital heart disease. In 80% of cases, TOF behaves as a complex genetic condition exhibiting significant heritability. As yet, no common genetic variants influencing TOF risk have been robustly identified. METHODS AND RESULTS Two hundred and seven haplotype-tagging single nucleotide polymorphisms in 22 candidate genes ...
PURPOSE Six pheochromocytoma susceptibility genes causing distinct syndromes have been identified; approximately one of three of all pheochromocytoma patients carry a predisposing germline mutation. When four major genes (VHL, RET, SDHB, SDHD) are analyzed in a clinical laboratory, costs are approximately $3,400 per patient. The aim of the study is to systematically obtain a robust algorithm to...
Clinical characteristics. Hereditary hearing loss and deafness may be conductive, sensorineural, or a combination of both; syndromic (associated with malformations of the external ear or other organs or with medical problems involving other organ systems) or nonsyndromic (no associated visible abnormalities of the external ear or any related medical problems); and prelingual (before language de...
X-linked intellectual deficiency (XLID) is a large group of genetic disorders. MED12 gene causes syndromic and nonsyndromic forms of XLID. Only seven pathological mutations have been identified in this gene. Here, we report a novel mutation segregating with XLID phenotype. This mutation could be in favor of genotype-phenotype correlations.
We previously reported on nonrecurrent overlapping duplications at Xp11.22 in individuals with nonsyndromic intellectual disability (ID) harboring HSD17B10, HUWE1, and the microRNAs miR-98 and let-7f-2 in the smallest region of overlap. Here, we describe six additional individuals with nonsyndromic ID and overlapping microduplications that segregate in the families. High-resolution mapping of t...
BACKGROUND Suggestive, but not conclusive, studies implicate many genetic variants in oral cleft etiology. We used a large, ethnically homogenous study population to test whether reported associations between nonsyndromic oral clefts and 12 genes (CLPTM1, CRISPLD2, FGFR2, GABRB3, GLI2, IRF6, PTCH1, RARA, RYK, SATB2, SUMO1, TGFA) could be confirmed. METHODS Thirty-one single nucleotide polymor...
PURPOSE Retinitis pigmentosa (RP), the most genetically heterogeneous disorder in humans, actually represents a group of pigmentary retinopathies characterized by night blindness followed by visual-field loss. RP can appear as either syndromic or nonsyndromic. One of the most common forms of syndromic RP is Usher syndrome, characterized by the combination of RP, hearing loss, and vestibular dys...
BACKGROUND Controversy abounds as to how craniosynostosis affects intracranial volume and whether more extensive procedures achieve superior results. Intracranial volume and cephalic index were evaluated among nonsyndromic sagittal synostosis patients undergoing cranioplasty. METHODS Twenty-four children with isolated nonsyndromic sagittal synostosis underwent a total calvarial reconstruction...
USH2A mutations have been implicated in the disease etiology of several inherited diseases, including Usher syndrome type 2 (USH2), nonsyndromic retinitis pigmentosa (RP), and nonsyndromic deafness. The complex genetic and phenotypic spectrums relevant to USH2A defects make it difficult to manage patients with such mutations. In the present study, we aim to determine the genetic etiology and to...
