Ambry Genetics

Apr 27, 2022

The c.845C>T (p.S282L) alteration is located in exon 8 (coding exon 7) of the MAMSTR gene. This alteration results from a C to T substitution at nucleotide position 845, causing the serine (S) at amino acid position 282 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
