Genes affected

SALL3 (HGNC:10527): (spalt like transcription factor 3) This gene encodes a sal-like C2H2-type zinc-finger protein, and belongs to a family of evolutionarily conserved genes found in species as diverse as Drosophila, C. elegans, and vertebrates. Mutations in some of these genes are associated with congenital disorders in human, suggesting their importance in embryonic development. This protein binds to DNA methyltransferase 3 alpha (DNMT3A), and reduces DNMT3A-mediated CpG island methylation. It is suggested that silencing of this gene, resulting in acceleration of DNA methylation, may have a role in oncogenesis. [provided by RefSeq, Oct 2011]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.330G>C (p.E110D) alteration is located in exon 2 (coding exon 2) of the SALL3 gene. This alteration results from a G to C substitution at nucleotide position 330, causing the glutamic acid (E) at amino acid position 110 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
