Genes affected

BAALC (HGNC:14333): (BAALC binder of MAP3K1 and KLF4) This gene was identified by gene expression studies in patients with acute myeloid leukemia (AML). The gene is conserved among mammals and is not found in lower organisms. Tissues that express this gene develop from the neuroectoderm. Multiple alternatively spliced transcript variants that encode different proteins have been described for this gene; however, some of the transcript variants are found only in AML cell lines.

The c.398T>C (p.M133T) alteration is located in exon 3 (coding exon 3) of the BAALC gene. This alteration results from a T to C substitution at nucleotide position 398, causing the methionine (M) at amino acid position 133 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
