Genes affected

DEFB108B (HGNC:29966): (defensin beta 108B) 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. A pseudogene of this gene has been found on chromosome 8. [provided by RefSeq, Oct 2014]

The c.188C>A (p.P63Q) alteration is located in exon 2 (coding exon 2) of the DEFB108B gene. This alteration results from a C to A substitution at nucleotide position 188, causing the proline (P) at amino acid position 63 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
