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]

The c.787G>A (p.D263N) alteration is located in exon 7 (coding exon 6) of the TNFAIP1 gene. This alteration results from a G to A substitution at nucleotide position 787, causing the aspartic acid (D) at amino acid position 263 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
