Ambry Genetics

Dec 19, 2023

The c.688C>T (p.R230W) alteration is located in exon 8 (coding exon 7) of the PAPLN gene. This alteration results from a C to T substitution at nucleotide position 688, causing the arginine (R) at amino acid position 230 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
