The c.8660C>T (p.A2887V) alteration is located in exon 29 (coding exon 28) of the TNRC18 gene. This alteration results from a C to T substitution at nucleotide position 8660, causing the alanine (A) at amino acid position 2887 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
