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.35T>A (p.F12Y) alteration is located in exon 1 (coding exon 1) of the DEFB110 gene. This alteration results from a T to A substitution at nucleotide position 35, causing the phenylalanine (F) at amino acid position 12 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
