Genes affected

WNT9B (HGNC:12779): (Wnt family member 9B) The WNT gene family consists of structurally related genes that 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. Study of its expression in the teratocarcinoma cell line NT2 suggests that it may be implicated in the early process of neuronal differentiation of NT2 cells induced by retinoic acid. This gene is clustered with WNT3, another family member, in the chromosome 17q21 region. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.280C>T (p.R94W) alteration is located in exon 2 (coding exon 2) of the WNT9B gene. This alteration results from a C to T substitution at nucleotide position 280, causing the arginine (R) at amino acid position 94 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
