The c.640G>T (p.V214L) alteration is located in exon 6 (coding exon 5) of the TMPRSS7 gene. This alteration results from a G to T substitution at nucleotide position 640, causing the valine (V) at amino acid position 214 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
