Genes affected
DEFB135 (HGNC:32400): (defensin beta 135) 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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 13, 2022The c.56T>G (p.V19G) alteration is located in exon 1 (coding exon 1) of the DEFB135 gene. This alteration results from a T to G substitution at nucleotide position 56, causing the valine (V) at amino acid position 19 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
