Genes affected
SALL1 (HGNC:10524): (spalt like transcription factor 1) The protein encoded by this gene is a zinc finger transcriptional repressor and may be part of the NuRD histone deacetylase complex (HDAC). Defects in this gene are a cause of Townes-Brocks syndrome (TBS) as well as bronchio-oto-renal syndrome (BOR). Two transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2022The c.3938G>A (p.R1313H) alteration is located in exon 3 (coding exon 3) of the SALL1 gene. This alteration results from a G to A substitution at nucleotide position 3938, causing the arginine (R) at amino acid position 1313 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Townes syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJan 01, 2023In 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. 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. ClinVar contains an entry for this variant (Variation ID: 426902). This variant has not been reported in the literature in individuals affected with SALL1-related conditions. This variant is present in population databases (rs529030284, gnomAD 0.06%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1313 of the SALL1 protein (p.Arg1313His). -
