Genes affected

DEFB116 (HGNC:18097): (defensin beta 116) 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. [provided by RefSeq, Oct 2014]

The c.179C>A (p.T60N) alteration is located in exon 2 (coding exon 2) of the DEFB116 gene. This alteration results from a C to A substitution at nucleotide position 179, causing the threonine (T) at amino acid position 60 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
