Genes affected

TNFAIP2 (HGNC:11895): (TNF alpha induced protein 2) This gene was identified as a gene whose expression can be induced by the tumor necrosis factor alpha (TNF) in umbilical vein endothelial cells. The expression of this gene was shown to be induced by retinoic acid in a cell line expressing a oncogenic version of the retinoic acid receptor alpha fusion protein, which suggested that this gene may be a retinoic acid target gene in acute promyelocytic leukemia.

Ambry Genetics

Dec 14, 2021

The c.271C>G (p.L91V) alteration is located in exon 2 (coding exon 2) of the TNFAIP2 gene. This alteration results from a C to G substitution at nucleotide position 271, causing the leucine (L) at amino acid position 91 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
