The c.3209G>A (p.R1070Q) alteration is located in exon 14 (coding exon 14) of the KIAA1755 gene. This alteration results from a G to A substitution at nucleotide position 3209, causing the arginine (R) at amino acid position 1070 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
