Genes affected

LASP1 (HGNC:6513): (LIM and SH3 protein 1) This gene encodes a member of a subfamily of LIM proteins, characterized by a LIM motif and a domain of Src homology region 3, and also a member of the nebulin family of actin-binding proteins. The encoded protein is a cAMP and cGMP dependent signaling protein and binds to the actin cytoskeleton at extensions of the cell membrane. The encoded protein has been linked to metastatic breast cancer, hematopoetic tumors such as B-cell lymphomas, and colorectal cancer. [provided by RefSeq, Oct 2012]

The c.415A>G (p.M139V) alteration is located in exon 5 (coding exon 5) of the LASP1 gene. This alteration results from a A to G substitution at nucleotide position 415, causing the methionine (M) at amino acid position 139 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
