Presentation
Accelerated atherosclerosis has been a proposed cause for the neurologic complications but is not universally present. [n.neurology.org]
We present a novel mutation (NM_014140.3:c.2070 2insT) that results in defective SMARCAL1 mRNA splicing in a child with SIOD. [ncbi.nlm.nih.gov]
Individuals with the mild presentation typically survive into adulthood if renal complications are treated. [sema4genomics.com]

Kidney Failure
Life expectancy is limited to childhood or early adolescence in most patients, due to stroke, severe opportunistic infections, bone marrow failure, complications of kidney failure, congestive heart failure, and unspecified lung disease. [cags.org.ae]
Complications of the severe form of SIOD can include strokes, severe opportunistic infections, bone marrow failure, and kidney failure that can be life-threatening early in life. [diseaseinfosearch.org]

Causes of death may include stroke, severe opportunistic infection, bone marrow failure, complications of kidney failure, congestive heart failure, or lung disease. Those with milder symptoms survive into adulthood if kidney disease is well-managed. [rarediseases.info.nih.gov]

Microscopic Hematuria
Of 512 consecutive prospective donors, 14 (2.7%) continued to have asymptomatic, microscopic hematuria over 1 month. [scinapse.io]
Microscopic hematuria was present in only one patient at disease onset. Focal segmental glomerulosclerosis (FSGS) was found in 82% of biopsies, including three differentiated as collapsing and one as hilar lesion subtypes. [journals.plos.org]

However, the molecular genetic workup can be performed in two steps: MLPA, followed by sequencing of the coding regions and splice sites (Grimm et al 2012). [healthdocbox.com]

Prognosis
Prognosis - Schimke immunoosseous dysplasia Not supplied. [checkorphan.org]
Asymptomatic, microscopic hematuria is seen in 8-21% of the general population, has a good prognosis, and is generally not an indication for kidney biopsy. But whether it should preclude kidney donation is unclear. Methods. [scinapse.io]
Our experience highlighted the importance of detailed clinical evaluation, appropriate genetic counseling and molecular testing, to provide timely treatment and more accurate prognosis. [bmcnephrol.biomedcentral.com]

Etiology
The representation of T-cell subsets in SIOD patients is further characterized by a high proportion of memory (CD45RA CD45RO ) T cells, however, the etiology of T-cell immunodeficiency has not been elucidated. [bloodjournal.org]
To the best of our knowledge, this is a hitherto new syndrome with most probably autosomal recessive inheritance and unknown etiology. [scinapse.io]
Cleft palate is also addressed, with details on etiology, phenotypes, treatment timing and approaches, and dental management. [books.google.it]
Studies of mitochondrial function and nitrous oxide production have not detected any impairment; therefore, empiric treatments addressing such etiologies would be expected to have little effect [ Lücke et al 2005b, Lücke et al 2006b ]. [ncbi.nlm.nih.gov]
The aim of this study was to evaluate the ability of a combination of MLPA kits to establish the etiologic diagnosis in a group of patients with syndromic ID. [healthdocbox.com]
