Genes affected
PKNOX1 (HGNC:9022): (PBX/knotted 1 homeobox 1) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in angiogenesis and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within camera-type eye development; hemopoiesis; and positive regulation of transcription by RNA polymerase II. Predicted to be located in cytoplasm and nucleus. Predicted to be part of chromatin. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 27, 2022The c.280G>A (p.E94K) alteration is located in exon 4 (coding exon 3) of the PKNOX1 gene. This alteration results from a G to A substitution at nucleotide position 280, causing the glutamic acid (E) at amino acid position 94 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
