Genes affected

POU6F2 (HGNC:21694): (POU class 6 homeobox 2) This gene encodes a member of the POU protein family characterized by the presence of a bipartite DNA binding domain, consisting of a POU-specific domain and a homeodomain, separated by a variable polylinker. The DNA binding domain may bind to DNA as monomers or as homo- and/or heterodimers, in a sequence-specific manner. The POU family members are transcriptional regulators, many of which are known to control cell type-specific differentiation pathways. This gene is a tumor suppressor involved in Wilms tumor (WT) predisposition. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.[provided by RefSeq, Oct 2009]

The c.317T>C (p.V106A) alteration is located in exon 5 (coding exon 4) of the POU6F2 gene. This alteration results from a T to C substitution at nucleotide position 317, causing the valine (V) at amino acid position 106 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
