Genes affected

DEFB136 (HGNC:34433): (defensin beta 136) Defensins are cysteine-rich cationic polypeptides that are important in the immunologic response to invading microorganisms. The antimicrobial protein encoded by this gene is secreted and is a member of the beta defensin protein family. Beta defensin genes are found in several clusters throughout the genome, with this gene mapping to a cluster at 8p23. [provided by RefSeq, Nov 2014]

Oct 25, 2024

The c.211C>G (p.Q71E) alteration is located in exon 2 (coding exon 2) of the DEFB136 gene. This alteration results from a C to G substitution at nucleotide position 211, causing the glutamine (Q) at amino acid position 71 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
