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 28, 2024The c.482G>A (p.S161N) alteration is located in exon 5 (coding exon 4) of the PKNOX1 gene. This alteration results from a G to A substitution at nucleotide position 482, causing the serine (S) at amino acid position 161 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
