Variant summary

Our verdict is Pathogenic. The variant received 10 ACMG points: 10P and 0B. PVS1 PM2

The NM_182758.4(WDR72):​c.1407T>G​(p.Tyr469*) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. Y469Y) has been classified as Benign. Variant results in nonsense mediated mRNA decay.

Genes affected

WDR72 (HGNC:26790): (WD repeat domain 72) This gene encodes a protein with eight WD-40 repeats. Mutations in this gene have been associated with amelogenesis imperfecta hypomaturation type 2A3. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2013]
