The c.619A>G (p.I207V) alteration is located in exon 3 (coding exon 3) of the TRIM77 gene. This alteration results from a A to G substitution at nucleotide position 619, causing the isoleucine (I) at amino acid position 207 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
