In OMIM this gene is associated with Schimke immunoosseous dysplasia. One of the diagnostic features of this disorder is T-cell immunodeficiency. OMIM reports that Boerkoel et al. (2002) (PMID: 11799392) determined that mutations in SMARCAL1 are responsible for SIOD. They looked at patients from 26 unrelated families and observed that affected individuals from 13 of 23 families with severe disease had 2 alleles with nonsense, frameshift, or splicing mutations, whereas affected individuals from 3 of 3 families with milder disease had a missense mutation on each allele. These observations indicated that some missense mutations allow retention of partial SMARCAL1 function and thus cause milder disease. Clewing et al. (2007)(PMID: 17089404) stated that 43 different mutations in the SMARCAL1 gene had been identified. They found that in 4 patients with a presumed monoallelic, heterozygous mutation in the SMARCAL1 gene, expressed RNA and/or protein from the other allele was not found, suggesting that in fact these 4 patients had biallelic SMARCAL1 mutations, though the second mutation was not found. Gene2Phenotype has a confirmed disease association between SMARCAL1 and Schimke immuno-osseous dysplasia. Rating this gene green as >3 cases of likely disease causing variants.Created: 16 May 2018, 10:48 a.m.

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s)
GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.Created: 19 Apr 2018, 3:01 p.m.
