The c.2909G>A (p.R970Q) alteration is located in exon 14 (coding exon 13) of the ZCCHC6 gene. This alteration results from a G to A substitution at nucleotide position 2909, causing the arginine (R) at amino acid position 970 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
