Genes affected

LYZL4 (HGNC:28387): (lysozyme like 4) Lysozymes (see LYZ; MIM 153450), especially C-type lysozymes, are well-recognized bacteriolytic factors widely distributed in the animal kingdom and play a mainly protective role in host defense. LYZL4 is a member of a family of lysozyme-like genes (Zhang et al., 2005 [PubMed 16014814]).[supplied by OMIM, Apr 2009]

Ambry Genetics

May 30, 2023

The c.340A>C (p.I114L) alteration is located in exon 4 (coding exon 3) of the LYZL4 gene. This alteration results from a A to C substitution at nucleotide position 340, causing the isoleucine (I) at amino acid position 114 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
