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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2022The c.172G>A (p.G58S) alteration is located in exon 2 (coding exon 2) of the IRX6 gene. This alteration results from a G to A substitution at nucleotide position 172, causing the glycine (G) at amino acid position 58 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
