Genes affected

LRRC4 (HGNC:15586): (leucine rich repeat containing 4) Predicted to be involved in modulation of chemical synaptic transmission and synapse organization. Predicted to act upstream of or within synapse organization. Predicted to be located in neuron spine and postsynaptic membrane. Predicted to be active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and plasma membrane. Predicted to be integral component of postsynaptic density membrane.

LRRC4 links:

SND1 (HGNC:30646): (staphylococcal nuclease and tudor domain containing 1) This gene encodes a transcriptional co-activator that interacts with the acidic domain of Epstein-Barr virus nuclear antigen 2 (EBNA 2), a transcriptional activator that is required for B-lymphocyte transformation. Other transcription factors that interact with this protein are signal transducers and activators of transcription, STATs. This protein is also thought to be essential for normal cell growth. A similar protein in mammals and other organisms is a component of the RNA-induced silencing complex (RISC). [provided by RefSeq, Jul 2016]

Ambry Genetics

Aug 15, 2023

The c.1397C>T (p.P466L) alteration is located in exon 2 (coding exon 1) of the LRRC4 gene. This alteration results from a C to T substitution at nucleotide position 1397, causing the proline (P) at amino acid position 466 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
