Genes affected

LRCH4 (HGNC:6691): (leucine rich repeats and calponin homology domain containing 4) This gene encodes a protein that contains leucine-rich repeats (LRR) at its amino terminus and that is known to be involved in ligand binding. The carboxyl terminus may act as a membrane anchor. Identified structural elements suggest that the encoded protein resembles a receptor. [provided by RefSeq, Jul 2008]

Jul 25, 2023

The c.1432C>T (p.P478S) alteration is located in exon 13 (coding exon 13) of the LRCH4 gene. This alteration results from a C to T substitution at nucleotide position 1432, causing the proline (P) at amino acid position 478 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
