The c.851G>A (p.R284Q) alteration is located in exon 4 (coding exon 4) of the THAP7 gene. This alteration results from a G to A substitution at nucleotide position 851, causing the arginine (R) at amino acid position 284 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
