Genes affected

TNFRSF17 (HGNC:11913): (TNF receptor superfamily member 17) The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is preferentially expressed in mature B lymphocytes, and may be important for B cell development and autoimmune response. This receptor has been shown to specifically bind to the tumor necrosis factor (ligand) superfamily, member 13b (TNFSF13B/TALL-1/BAFF), and to lead to NF-kappaB and MAPK8/JNK activation. This receptor also binds to various TRAF family members, and thus may transduce signals for cell survival and proliferation. [provided by RefSeq, Jul 2008]

NPIPB2 (HGNC:37451): (nuclear pore complex interacting protein family member B2) Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

NPIPB2 (HGNC:):

The c.331G>A (p.D111N) alteration is located in exon 3 (coding exon 3) of the TNFRSF17 gene. This alteration results from a G to A substitution at nucleotide position 331, causing the aspartic acid (D) at amino acid position 111 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
