The c.2368C>A (p.P790T) 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 2368, causing the proline (P) at amino acid position 790 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
