Genes affected

LCP2 (HGNC:6529): (lymphocyte cytosolic protein 2) This gene encodes an adapter protein that acts as a substrate of the T cell antigen receptor (TCR)-activated protein tyrosine kinase pathway. The encoded protein associates with growth factor receptor bound protein 2, and is thought to play a role TCR-mediated intracellular signal transduction. A similar protein in mouse plays a role in normal T-cell development and activation. Mice lacking this gene show subcutaneous and intraperitoneal fetal hemorrhaging, dysfunctional platelets and impaired viability. [provided by RefSeq, Nov 2016]

Ambry Genetics

May 13, 2024

The c.1222C>A (p.P408T) alteration is located in exon 18 (coding exon 18) of the LCP2 gene. This alteration results from a C to A substitution at nucleotide position 1222, causing the proline (P) at amino acid position 408 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
