The c.8616C>A (p.H2872Q) alteration is located in exon 28 (coding exon 27) of the TNRC18 gene. This alteration results from a C to A substitution at nucleotide position 8616, causing the histidine (H) at amino acid position 2872 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
