Genes affected

IRX4 (HGNC:6129): (iroquois homeobox 4) Predicted to enable DNA-binding transcription factor 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 by RNA polymerase II. Predicted to act upstream of or within heart development. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

The c.1382A>G (p.K461R) alteration is located in exon 5 (coding exon 5) of the IRX4 gene. This alteration results from a A to G substitution at nucleotide position 1382, causing the lysine (K) at amino acid position 461 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
