Ambry Genetics

Apr 05, 2023

The c.757C>T (p.R253C) alteration is located in exon 4 (coding exon 2) of the SPSB4 gene. This alteration results from a C to T substitution at nucleotide position 757, causing the arginine (R) at amino acid position 253 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
