Genes affected

LNX1 (HGNC:6657): (ligand of numb-protein X 1) This gene encodes a membrane-bound protein that is involved in signal transduction and protein interactions. The encoded product is an E3 ubiquitin-protein ligase, which mediates ubiquitination and subsequent proteasomal degradation of proteins containing phosphotyrosine binding (PTB) domains. This protein may play an important role in tumorogenesis. Alternatively spliced transcript variants encoding distinct isoforms have been described. A pseudogene, which is located on chromosome 17, has been identified for this gene. [provided by RefSeq, Jul 2008]

The c.841G>C (p.D281H) alteration is located in exon 5 (coding exon 4) of the LNX1 gene. This alteration results from a G to C substitution at nucleotide position 841, causing the aspartic acid (D) at amino acid position 281 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
