The c.1157A>G (p.Y386C) alteration is located in exon 6 (coding exon 6) of the TRIM64B gene. This alteration results from a A to G substitution at nucleotide position 1157, causing the tyrosine (Y) at amino acid position 386 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
