The c.3202G>A (p.E1068K) alteration is located in exon 17 (coding exon 16) of the TRIM66 gene. This alteration results from a G to A substitution at nucleotide position 3202, causing the glutamic acid (E) at amino acid position 1068 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
