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. -
