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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2024The c.253A>G (p.T85A) alteration is located in exon 2 (coding exon 2) of the BAALC gene. This alteration results from a A to G substitution at nucleotide position 253, causing the threonine (T) at amino acid position 85 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
