Genes affected
SALL4 (HGNC:15924): (spalt like transcription factor 4) This gene encodes a zinc finger transcription factor thought to play a role in the development of abducens motor neurons. Defects in this gene are a cause of Duane-radial ray syndrome (DRRS). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]

Submissions by phenotype

Duane-radial ray syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 07, 2023This variant has not been reported in the literature in individuals affected with SALL4-related conditions. This variant is present in population databases (rs373555761, gnomAD 0.01%). This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1051 of the SALL4 protein (p.Ala1051Val). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
