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]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

Collection Method: clinical testing

The c.307G>T (p.A103S) alteration is located in exon 5 (coding exon 4) of the POU6F2 gene. This alteration results from a G to T substitution at nucleotide position 307, causing the alanine (A) at amino acid position 103 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
