BACKGROUND Schimke immuno-osseous dysplasia (SIOD) is a multisystemic disorder caused by biallelic mutations in the SWI/SNF-related matrix-associated actin-dependent regulator of chromatin, subfamily A-like 1 (SMARCAL1) gene. Changes in gene expression underlie the arteriosclerosis and T-cell immunodeficiency of SIOD; therefore, we hypothesized that SMARCAL1 deficiency causes the focal segmenta...
BACKGROUND Schimke immuno-osseous dysplasia (SIOD, OMIM #242900) is an autosomal-recessive pleiotropic disorder characterized by spondyloepiphyseal dysplasia, renal dysfunction and T-cell immunodeficiency. SIOD is caused by mutations in the gene SMARCAL1. CASE PRESENTATION We report the clinical and genetic diagnosis of a 5-years old girl with SIOD, referred to our Center because of nephrotic...
Schimke immuno-osseous dysplasia (SIOD) is characterised by autosomal recessive inheritance, spondyloepiphyseal dysplasia causing growth retardation, defective cellular immunity, progressive nephropathy leading to renal failure, hyperpigmented macules, and dysmorphic facial features. Half of SIOD patients also have hypothyroidism, half episodic cerebral ischaemia, and a tenth bone marrow failur...
The SNF2 gene family consists of a large group of proteins involved in transcriptional regulation, maintenance of chromosome integrity, and various aspects of DNA repair. We cloned a novel SNF2 family human cDNA, with sequence identity to the Escherichia coli RNA polymerase-binding protein HepA and named the human hepA-related protein (HHARP/SMARCAL1). In addition, the mouse ortholog (Mharp/Sma...
Schimke immuno-osseous dysplasia (OMIM 242900) is an uncommon autosomal-recessive multisystem disease caused by mutations in SMARCAL1 (swi/snf-related, matrix-associated, actin-dependent regulator of chromatin, subfamily a-like 1), a gene encoding a putative chromatin remodeling protein. Neurologic manifestations identified to date relate to enhanced atherosclerosis and cerebrovascular disease....
schimke immuno-osseous dysplasia is a rare autosomal recessive multisystem disorder characterized by steroid-resistant nephrotic syndrome, immunodeficiency, and spondyloepiphy-seal dysplasia. mutations in swi/snf2 related, matrix associated, actin dependent regulator of chromatin, subfamily a-like 1 (smarcal1) gene are responsible for the disease. the present report describes, for the first tim...
DNA damage and other forms of replication stress can cause replication forks to stall. Replication stress response proteins stabilize and resolve stalled forks by mechanisms that include fork remodeling to facilitate repair or bypass of damaged templates. Several enzymes including SMARCAL1, HLTF, and ZRANB3 catalyze these reactions. SMARCAL1 and HLTF utilize structurally distinct accessory doma...
Schimke immuno-osseous dysplasia is a rare autosomal recessive multisystem disorder characterized by steroid-resistant nephrotic syndrome, immunodeficiency, and spondyloepiphy-seal dysplasia. Mutations in SWI/SNF2 related, matrix associated, actin dependent regulator of chromatin, subfamily a-like 1 (SMARCAL1) gene are responsible for the disease. The present report describes, for the f...
Brca2 deficiency causes Mre11-dependent degradation of nascent DNA at stalled forks, leading to cell lethality. To understand the molecular mechanisms underlying this process, we isolated Xenopus laevis Brca2. We demonstrated that Brca2 protein prevents single-stranded DNA gap accumulation at replication fork junctions and behind them by promoting Rad51 binding to replicating DNA. Without Brca2...
