Genes affected

SMARCAL1 (HGNC:11102): (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a like 1) The protein encoded by this gene is a member of the SWI/SNF family of proteins. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. The encoded protein shows sequence similarity to the E. coli RNA polymerase-binding protein HepA. Mutations in this gene are a cause of Schimke immunoosseous dysplasia (SIOD), an autosomal recessive disorder with the diagnostic features of spondyloepiphyseal dysplasia, renal dysfunction, and T-cell immunodeficiency.

Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals affected with SMARCAL1-related conditions. This sequence change replaces glutamine, which is neutral and polar, with glutamic acid, which is acidic and polar, at codon 9 of the SMARCAL1 protein (p.Gln9Glu). This variant is not present in population databases (gnomAD no frequency). -
