Genes affected

WNT10A (HGNC:13829): (Wnt family member 10A) The WNT gene family consists of structurally related genes which encode secreted signaling proteins. These proteins have been implicated in oncogenesis and in several developmental processes, including regulation of cell fate and patterning during embryogenesis. This gene is a member of the WNT gene family. It is strongly expressed in the cell lines of promyelocytic leukemia and Burkitt's lymphoma. In addition, it and another family member, the WNT6 gene, are strongly coexpressed in colorectal cancer cell lines. The gene overexpression may play key roles in carcinogenesis through activation of the WNT-beta-catenin-TCF signaling pathway. This gene and the WNT6 gene are clustered in the chromosome 2q35 region.

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 and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -

Review Status: no assertion criteria provided

Collection Method: clinical testing

The WNT10A c.208C>T variant is predicted to result in the amino acid substitution p.Arg70Trp. This variant has been reported in the heterozygous state in two brothers with missing permanent teeth, and one of the two brothers has more severe phenotype also carried a truncating variant in the EDARADD gene (Arte et al. 2013. PubMed ID: 23991204). This variant is documented in 0.59% of alleles in individuals of South Asian descent in gnomAD. This variant could be benign. At this time, the clinical significance of this variant is uncertain due to insufficient functional and genetic evidence. -
