Ambry Genetics

Aug 17, 2021

The c.49C>T (p.R17C) alteration is located in exon 1 (coding exon 1) of the MALSU1 gene. This alteration results from a C to T substitution at nucleotide position 49, causing the arginine (R) at amino acid position 17 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
