Genes affected

LPP (HGNC:6679): (LIM domain containing preferred translocation partner in lipoma) This gene encodes a member of a subfamily of LIM domain proteins that are characterized by an N-terminal proline-rich region and three C-terminal LIM domains. The encoded protein localizes to the cell periphery in focal adhesions and may be involved in cell-cell adhesion and cell motility. This protein also shuttles through the nucleus and may function as a transcriptional co-activator. This gene is located at the junction of certain disease-related chromosomal translocations, which result in the expression of chimeric proteins that may promote tumor growth. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

The c.169C>G (p.P57A) alteration is located in exon 3 (coding exon 1) of the LPP gene. This alteration results from a C to G substitution at nucleotide position 169, causing the proline (P) at amino acid position 57 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
