Genes affected
PKNOX2 (HGNC:16714): (PBX/knotted 1 homeobox 2) Homeodomain proteins are sequence-specific transcription factors that share a highly conserved DNA-binding domain and play fundamental roles in cell proliferation, differentiation, and death. PKNOX2 belongs to the TALE (3-amino acid loop extension) class of homeodomain proteins characterized by a 3-amino acid extension between alpha helices 1 and 2 within the homeodomain (Imoto et al., 2001 [PubMed 11549286]).[supplied by OMIM, Oct 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2024The c.173G>A (p.S58N) alteration is located in exon 5 (coding exon 2) of the PKNOX2 gene. This alteration results from a G to A substitution at nucleotide position 173, causing the serine (S) at amino acid position 58 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
