Genes affected

IRX5 (HGNC:14361): (iroquois homeobox 5) This gene encodes a member of the iroquois homeobox gene family, which are involved in several embryonic developmental processes. Knockout mice lacking this gene show that it is required for retinal cone bipolar cell differentiation, and that it negatively regulates potassium channel gene expression in the heart to ensure coordinated cardiac repolarization. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

Collection Method: clinical testing

The c.113G>T (p.R38L) alteration is located in exon 1 (coding exon 1) of the IRX5 gene. This alteration results from a G to T substitution at nucleotide position 113, causing the arginine (R) at amino acid position 38 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
