Ring Chromosome 18: A Case Report
Ring chromosomes are rare chromosomal disorders that usually appear to occur de novo. A ring chromosome forms when due to deletion both ends of chromosome fuse with each other. Depending on the amount of chromosomal deletion, the clinical manifestations may be different. So, ring 18 syndrome is characterized by severe mental growth retardation as well as microcephaly, brain and ocular malformat...
متن کاملD13 ring chromosome syndrome.
A case of ring D13 chromosome, confirmed by trypsin banding, is described. Reviewing 21 cases from published reports, the most common features of this syndrome are microcephaly and associated mental retardation, poor uterine growth, deformed auricles, hypertelorism, epicanthus, broad nasal bridge, and genital defects in males.
متن کاملRing chromosome 17 epilepsy may resemble that of ring chromosome 20 syndrome.
A four-year-old boy with ring chromosome 17 presenting with early-onset, pharmacoresistant epilepsy underwent repeated 24-hour video-EEG monitoring and cytogenetic analyses, including fluorescent in situ hybridization with telomeric and locus-specific probes of chromosome 17. Epilepsy was characterized by nocturnal motor seizures and by prolonged diurnal electrical status epilepticus. The 46, X...
متن کاملA locus for generalized tonic-clonic seizure susceptibility maps to chromosome 10q25-q26.
Inheritance patterns in twins and multiplex families led us to hypothesize that two loci were segregating in subjects with juvenile myoclonic epilepsy (JME), one predisposing to generalized tonic-clonic seizures (GTCS) and a second to myoclonic seizures. We tested this hypothesis by performing genome-wide scan of a large family (Family 01) and used the results to guide analyses of additional fa...
متن کاملFAM53B truncation caused by t(10;19)(q26;q13) chromosome translocation in acute lymphoblastic leukemia
RNA-sequencing of the patient's bone marrow detected fusion transcripts in which the coding sequence of the FAM53B gene (from 10q26) was fused to a genomic sequence (from 19q13) that mapped upstream of the SLC7A10 locus. Reverse transcription-polymerase chain reaction together with Sanger sequencing verified the presence of this fusion transcript. The FAM53B fusion transcript is not expected to...
