Genes affected
AFF3 (HGNC:6473): (ALF transcription elongation factor 3) This gene encodes a tissue-restricted nuclear transcriptional activator that is preferentially expressed in lymphoid tissue. Isolation of this protein initially defined a highly conserved LAF4/MLLT2 gene family of nuclear transcription factors that may function in lymphoid development and oncogenesis. In some ALL patients, this gene has been found fused to the gene for MLL. Multiple alternatively spliced transcript variants that encode different proteins have been found for this gene.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.3112G>A (p.E1038K) alteration is located in exon 19 (coding exon 18) of the AFF3 gene. This alteration results from a G to A substitution at nucleotide position 3112, causing the glutamic acid (E) at amino acid position 1038 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
