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]

The c.584C>T (p.A195V) alteration is located in exon 6 (coding exon 5) of the PKNOX1 gene. This alteration results from a C to T substitution at nucleotide position 584, causing the alanine (A) at amino acid position 195 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
