Genes affected

ZHX2 (HGNC:18513): (zinc fingers and homeoboxes 2) The members of the zinc fingers and homeoboxes gene family are nuclear homodimeric transcriptional repressors that interact with the A subunit of nuclear factor-Y (NF-YA) and contain two C2H2-type zinc fingers and five homeobox DNA-binding domains. This gene encodes member 2 of this gene family. In addition to forming homodimers, this protein heterodimerizes with member 1 of the zinc fingers and homeoboxes family.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.251C>G (p.P84R) alteration is located in exon 3 (coding exon 1) of the ZHX2 gene. This alteration results from a C to G substitution at nucleotide position 251, causing the proline (P) at amino acid position 84 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
