Ambry Genetics

Jun 02, 2024

The c.325A>T (p.S109C) alteration is located in exon 2 (coding exon 2) of the QPCTL gene. This alteration results from a A to T substitution at nucleotide position 325, causing the serine (S) at amino acid position 109 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
