A de novo POU3F3 Deletion in a Boy with Intellectual Disability and Dysmorphic Features.
We describe a boy presenting with intellectual disability and dysmorphic features in whom a cryptic microdeletion in chromosome band 2q12.1 was identified with array CGH. The deletion results in a loss of the POU3F3 and MRPS9 genes. In this paper, we discuss the possible role of POU3F3 haploinsufficiency in relation to the boy's phenotype.
متن کاملPartial monosomy 3q in a boy with short stature, developmental delay, and mild dysmorphic features.
We describe the clinical and cytogenetic findings in a boy with an unbalanced karyotype involving monosomy for 3q27-q29. He does not resemble other reported cases of del(3q). Deletions of the long arm of chromosome 3 are extremely rare, having been reported in five cases, only two of which had terminal 3q deletions.
متن کاملA Case of 17q21.31 Microduplication and 7q31.33 Microdeletion, Associated with Developmental Delay, Microcephaly, and Mild Dysmorphic Features
Concurrent cryptic microdeletion and microduplication syndromes have recently started to reveal themselves with the advent of microarray technology. Analysis has shown that low-copy repeats (LCRs) have allowed chromosome regions throughout the genome to become hotspots for nonallelic homologous recombination to take place. Here, we report a case of a 7.5-year-old girl who manifests microcephaly...
متن کاملA novel de novo 1.8 Mb microdeletion of 17q21.33 associated with intellectual disability and dysmorphic features.
We report on a de novo 17q21.33 microdeletion, 1.8 Mb in size, detected in a patient with mild intellectual disability, growth retardation, poor weight gain, microcephaly, long face, large beaked nose, thick lower lip, micrognathia and other dysmorphic features. The deletion was detected by whole-genome genotyping BeadChip assay and involves the genomic region between 45,682,246 and 47,544,816 ...
متن کاملDe novo pathogenic variants in CHAMP1 are associated with global developmental delay, intellectual disability, and dysmorphic facial features
We identified five unrelated individuals with significant global developmental delay and intellectual disability (ID), dysmorphic facial features and frequent microcephaly, and de novo predicted loss-of-function variants in chromosome alignment maintaining phosphoprotein 1 (CHAMP1). Our findings are consistent with recently reported de novo mutations in CHAMP1 in five other individuals with sim...
