Genes affected
DEFB134 (HGNC:32399): (defensin beta 134) 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 GeneticsMay 31, 2022The c.167T>C (p.L56P) alteration is located in exon 2 (coding exon 2) of the DEFB134 gene. This alteration results from a T to C substitution at nucleotide position 167, causing the leucine (L) at amino acid position 56 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
