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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 07, 2024The c.95C>A (p.T32N) alteration is located in exon 2 (coding exon 2) of the DEFB136 gene. This alteration results from a C to A substitution at nucleotide position 95, causing the threonine (T) at amino acid position 32 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
