Collection Method: clinical testing

The c.255C>G (p.D85E) alteration is located in exon 2 (coding exon 2) of the TREML4 gene. This alteration results from a C to G substitution at nucleotide position 255, causing the aspartic acid (D) at amino acid position 85 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
