Genes affected

DEFA5 (HGNC:2764): (defensin alpha 5) Defensins are a family of antimicrobial and cytotoxic peptides thought to be involved in host defense. They are abundant in the granules of neutrophils and also found in the epithelia of mucosal surfaces such as those of the intestine, respiratory tract, urinary tract, and vagina. Members of the defensin family are highly similar in protein sequence and distinguished by a conserved cysteine motif. Several of the alpha defensin genes appear to be clustered on chromosome 8. The protein encoded by this gene, defensin, alpha 5, is highly expressed in the secretory granules of Paneth cells of the ileum. [provided by RefSeq, Oct 2014]

May 04, 2022

The c.40G>A (p.A14T) alteration is located in exon 1 (coding exon 1) of the DEFA5 gene. This alteration results from a G to A substitution at nucleotide position 40, causing the alanine (A) at amino acid position 14 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
