Ambry Genetics

Apr 24, 2024

The c.3829C>T (p.P1277S) alteration is located in exon 32 (coding exon 31) of the SBNO2 gene. This alteration results from a C to T substitution at nucleotide position 3829, causing the proline (P) at amino acid position 1277 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
