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.

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 764 of the SMARCAL1 protein (p.Arg764Gln). This variant is present in population databases (rs267607071, gnomAD 0.006%). This missense change has been observed in individual(s) with Schimke immuno-osseous dysplasia (PMID: 11799392, 22998683). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 4178). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt SMARCAL1 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects SMARCAL1 function (PMID: 18805831, 18974355, 19793864, 23671665, 26089390). For these reasons, this variant has been classified as Pathogenic. -
