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.

Townes syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 13, 2016 | For these reasons, this variant has been classified as Pathogenic. While this particular variant has not been reported in the literature, loss-of-function variants in SALL1 are known to be pathogenic (PMID: 9973281, 16088922). This sequence change inserts 1 nucleotide in exon 2 of the SALL1 mRNA (c.1214dupC), causing a frameshift at codon 406. This creates a premature translational stop signal (p.Leu406Phefs*32) and is expected to result in an absent or disrupted protein product. - |
