Genes affected

DVL3 (HGNC:3087): (dishevelled segment polarity protein 3) This gene is a member of a multi-gene family which shares strong similarity with the Drosophila dishevelled gene, dsh. The Drosophila dishevelled gene encodes a cytoplasmic phosphoprotein that regulates cell proliferation. [provided by RefSeq, Jul 2008]

DVL3 Gene-Disease associations (from GenCC):

• autosomal dominant Robinow syndrome 3

  Inheritance: AD Classification: DEFINITIVE, STRONG Submitted by: G2P, Labcorp Genetics (formerly Invitae)
• autosomal dominant Robinow syndrome

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.187 CDS is truncated, and there are 3 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 3-184170352-GC-G is Pathogenic according to our data. Variant chr3-184170352-GC-G is described in ClinVar as Pathogenic. ClinVar VariationId is 219222.Status of the report is criteria_provided_single_submitter, 1 stars.
