COFS is a degenerative autosomal recessive disorder of prenatal onset affecting the brain, eye and spinal cord. After birth, it leads to brain atrophy, hypoplasia of the corpus callosum, hypotonia, cataracts, microcornea, optic atrophy, progressive joint contractures and growth failure. Facial dysmorphism is a constant feature. Abnormalities of the skull, eyes, limbs, heart and kidney also occur.

Publication Abstract from PubMed The human ERCC1/XPF complex is a structure-specific endonuclease with defined polarity that participates in multiple DNA repair pathways. We report the heterodimeric structure of the C-terminal domains of both proteins responsible for ERCC1/XPF complex formation. Both domains exhibit the double helix-hairpin-helix motif (HhH)2, and they are related by a pseudo-2-fold symmetry axis. In the XPF domain, the hairpin of the second motif is replaced by a short turn. The ERCC1 domain folds properly only in the presence of the XPF domain, which implies a role for XPF as a scaffold for the folding of ERCC1. The intersubunit interactions are largely hydrophobic in nature. NMR titration data show that only the ERCC1 domain of the ERCC1/XPF complex is involved in DNA binding. On the basis of these findings, we propose a model for the targeting of XPF nuclease via ERCC1-mediated interactions in the context of nucleotide excision repair. The structure of the human ERCC1/XPF interaction domains reveals a complementary role for the two proteins in nucleotide excision repair.,Tripsianes K, Folkers G, Ab E, Das D, Odijk H, Jaspers NG, Hoeijmakers JH, Kaptein R, Boelens R Structure. 2005 Dec;13(12):1849-58.
