The c.734G>A (p.R245Q) alteration is located in exon 9 (coding exon 7) of the KIAA1191 gene. This alteration results from a G to A substitution at nucleotide position 734, causing the arginine (R) at amino acid position 245 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
