Collection Method: clinical testing

The c.264G>T (p.K88N) alteration is located in exon 4 (coding exon 3) of the TMPRSS7 gene. This alteration results from a G to T substitution at nucleotide position 264, causing the lysine (K) at amino acid position 88 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
