Cerebro-oculo-facio-skeletal syndrome

چکیده
In this article, the author updates information on cerebro-oculo-facio-skeletal (COFS) syndrome. The condition is rare, with autosomal recessive inheritance, and manifests abnormal facies, ocular changes (eg, cataracts, retinal degeneration, microcornea, optic atrophy), in utero and postnatal growth retardation, severe psychomotor retardation, cerebral and cerebellar degeneration with calcification in basal ganglia and white matter, progressive joint contractures and wasting, and death in infancy or early childhood. In many instances, the disorder results from a mutation in the Cockayne syndrome group B (ERCC6/CSB) gene or xeroderma pigmentosum (ie, DNA repair) genes (ERCC2/XPD, ERCC5/XPG, ERCC1/XPF, or ERCC4), mirroring phenotypic and clinical similarities between these conditions.

22q11.2 duplication syndrome (OMIM #608363) was first described by Edelmann in 1999 and later by other groups. The syndrome presented with clinically normal to varied spectrum of multisystem involvement. The 22q11.2 duplication syndrome in comparison to the 22q11.2 micro-deletion is a relatively rare condition which inherited autosomal dominantly or may occur as de novo condition. This article ...

We describe an 8 months old Saudi girl, a product of consanguineous parents with unremarkable pre-natal and postnatal history and birth weight 2 kg. She was having microcephaly, micrognathia, micro-ophthalmia, large low set ears, upper lip overhanging the lower lip and congenital contractures. G...

Nucleotide excision repair (NER) is a genome caretaker mechanism responsible for removing helix-distorting DNA lesions, most notably ultraviolet photodimers. Inherited defects in NER result in profound photosensitivity and the cancer-prone syndrome xeroderma pigmentosum (XP) or two progeroid syndromes: Cockayne and trichothiodystrophy syndromes. The heterodimer ERCC1-XPF is one of two endonucle...

SUMMARY Three infants are described, one with the Neu-Laxova syndrome and two with the cerebro-oculo-facio-skeletal (COFS) syndrome. The relationship between these two syndromes is discussed in the light of the present cases and others in published reports. Pena and Shokeirl described ten infants with a syndrome consisting of microcephaly, microphthalmia, cataracts, and joint contractures and i...
