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.185T>C (p.L62P) alteration is located in exon 2 (coding exon 2) of the LRR1 gene. This alteration results from a T to C substitution at nucleotide position 185, causing the leucine (L) at amino acid position 62 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
