Genes affected

TNFAIP1 (HGNC:11894): (TNF alpha induced protein 1) This gene was identified as a gene whose expression can be induced by the tumor necrosis factor alpha (TNF) in umbilical vein endothelial cells. Studies of a similar gene in mouse suggest that the expression of this gene is developmentally regulated in a tissue-specific manner. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.740A>T (p.Y247F) alteration is located in exon 7 (coding exon 6) of the TNFAIP1 gene. This alteration results from a A to T substitution at nucleotide position 740, causing the tyrosine (Y) at amino acid position 247 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
