Genes affected

NFAM1 (HGNC:29872): (NFAT activating protein with ITAM motif 1) The protein encoded by this gene is a type I membrane receptor that activates cytokine gene promoters such as the IL-13 and TNF-alpha promoters. The encoded protein contains an immunoreceptor tyrosine-based activation motif (ITAM) and is thought to regulate the signaling and development of B-cells. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.685G>A (p.E229K) alteration is located in exon 5 (coding exon 5) of the NFAM1 gene. This alteration results from a G to A substitution at nucleotide position 685, causing the glutamic acid (E) at amino acid position 229 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
