Dec 08, 2023

The c.2250C>A (p.N750K) alteration is located in exon 13 (coding exon 12) of the IQUB gene. This alteration results from a C to A substitution at nucleotide position 2250, causing the asparagine (N) at amino acid position 750 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
