Genes affected

DEFB110 (HGNC:18091): (defensin beta 110) Defensins form a family of antimicrobial and cytotoxic peptides made by neutrophils. Defensins are short, processed peptide molecules that are classified by structure into three groups: alpha-defensins, beta-defensins and theta-defensins. All beta-defensin genes are densely clustered in four to five syntenic chromosomal regions. Two transcript variants encoding different isoforms have been found for this gene.

The c.95G>A (p.R32K) alteration is located in exon 2 (coding exon 2) of the DEFB110 gene. This alteration results from a G to A substitution at nucleotide position 95, causing the arginine (R) at amino acid position 32 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
