Ambry Genetics

Sep 07, 2022

The c.142C>T (p.P48S) alteration is located in exon 2 (coding exon 2) of the VSTM2B gene. This alteration results from a C to T substitution at nucleotide position 142, causing the proline (P) at amino acid position 48 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
