The c.3008A>G (p.Q1003R) alteration is located in exon 14 (coding exon 14) of the KIAA1755 gene. This alteration results from a A to G substitution at nucleotide position 3008, causing the glutamine (Q) at amino acid position 1003 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
