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]

This variant was observed in compound heterozygosity with NM_182758.3:c.2522T>A and is pathogenic for autosomal recessive OMIM:611590. These variants were observed by whole exome sequencing and Sanger sequencing in three patients. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
