Collection Method: clinical testing

The c.992G>A (p.G331E) alteration is located in exon 6 (coding exon 6) of the TRIM64B gene. This alteration results from a G to A substitution at nucleotide position 992, causing the glycine (G) at amino acid position 331 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
