Genes affected

PGLYRP4 (HGNC:30015): (peptidoglycan recognition protein 4) Summary: This gene encodes a peptidoglycan recognition protein, which belongs to the N-acetylmuramoyl-L-alanine amidase 2 family. These proteins are part of the innate immune system and recognize peptidoglycan, a ubiquitous component of bacterial cell walls. This antimicrobial protein binds to murein peptidoglycans of Gram-positive bacteria. [provided by RefSeq, Oct 2014]

The c.1083G>C (p.L361F) alteration is located in exon 9 (coding exon 8) of the PGLYRP4 gene. This alteration results from a G to C substitution at nucleotide position 1083, causing the leucine (L) at amino acid position 361 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
