Genes affected

IRX6 (HGNC:14675): (iroquois homeobox 6) Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific; DNA-binding transcription repressor activity, RNA polymerase II-specific; and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in cell development; neuron differentiation; and regulation of transcription, DNA-templated. Predicted to act upstream of or within detection of visible light; negative regulation of transcription, DNA-templated; and retina morphogenesis in camera-type eye. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Nov 30, 2022

The c.14A>G (p.H5R) alteration is located in exon 1 (coding exon 1) of the IRX6 gene. This alteration results from a A to G substitution at nucleotide position 14, causing the histidine (H) at amino acid position 5 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
