Ambry Genetics

Aug 26, 2022

The c.304C>T (p.P102S) alteration is located in exon 1 (coding exon 1) of the GALNT15 gene. This alteration results from a C to T substitution at nucleotide position 304, causing the proline (P) at amino acid position 102 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
