Genes affected
LRR1 (HGNC:19742): (leucine rich repeat protein 1) The protein encoded by this gene contains a leucine-rich repeat (LRR). It specifically interacts with TNFRSF9/4-1BB, a member of the tumor necrosis factor receptor (TNFR) superfamily. Overexpression of this gene suppresses the activation of NF-kappa B induced by TNFRSF9 or TNF receptor-associated factor 2 (TRAF2), which suggests that this protein is a negative regulator of TNFRSF9-mediated signaling cascades. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Feb 2011]

Collection Method: clinical testing

The c.475C>T (p.L159F) alteration is located in exon 3 (coding exon 3) of the LRR1 gene. This alteration results from a C to T substitution at nucleotide position 475, causing the leucine (L) at amino acid position 159 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
