Variant summary

Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_Strong BP6_Very_Strong BA1

The NM_001002035.2(DEFB108B):​c.158A>G​(p.Gln53Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.594 in 1,598,216 control chromosomes in the GnomAD database, including 287,314 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

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]

XNDC1N-ZNF705EP-ALG1L9P (HGNC:55871): (XNDC1N-ZNF705EP-ALG1L9P readthrough) This locus represents naturally occurring readthrough transcription between the neighboring XNDC1N (XRCC1 N-terminal domain containing 1-like), ZNF705P (zinc finger protein 705, pseudogene) and ALG1L9P (ALG1 like 9, pseudogene) genes on chromosome 11q13.4. These readthrough transcripts are candidates for nonsense-mediated mRNA decay (NMD), and are unlikely to produce a protein product. [provided by RefSeq, Aug 2021]

DEFB108B (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=3.5890794E-6).
• BP6: Variant 11-71837498-A-G is Benign according to our data. Variant chr11-71837498-A-G is described in ClinVar as [Benign]. Clinvar id is 768459.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.63 is higher than 0.05.
