The c.1250C>A (p.A417D) alteration is located in exon 5 (coding exon 5) of the IRX4 gene. This alteration results from a C to A substitution at nucleotide position 1250, causing the alanine (A) at amino acid position 417 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
