Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 2P and 10B. PM1BP4BP6BS1BS2

The NM_016373.4(WWOX):c.421G>A(p.Ala141Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000204 in 1,613,908 control chromosomes in the GnomAD database, including 7 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A141V) has been classified as Uncertain significance.

Genes affected

WWOX (HGNC:12799): (WW domain containing oxidoreductase) This gene encodes a member of the short-chain dehydrogenases/reductases (SDR) protein family. This gene spans the FRA16D common chromosomal fragile site and appears to function as a tumor suppressor gene. Expression of the encoded protein is able to induce apoptosis, while defects in this gene are associated with multiple types of cancer. Disruption of this gene is also associated with autosomal recessive spinocerebellar ataxia 12. Disruption of a similar gene in mouse results in impaired steroidogenesis, additionally suggesting a metabolic function for the protein. Alternative splicing results in multiple transcript variants.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 14 uncertain in NM_016373.4

BP4

Computational evidence support a benign effect (MetaRNN=0.3100425).

BP6

Variant 16-78164194-G-A is Benign according to our data. Variant chr16-78164194-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 410088.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000112 (17/152258) while in subpopulation SAS AF = 0.00166 (8/4816). AF 95% confidence interval is 0.000826. There are 0 homozygotes in GnomAd4. There are 11 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 7 AR,AD gene
