Collection Method: clinical testing

The c.588G>C (p.K196N) alteration is located in exon 5 (coding exon 5) of the TREML4 gene. This alteration results from a G to C substitution at nucleotide position 588, causing the lysine (K) at amino acid position 196 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
