Ambry Genetics

Apr 13, 2023

The c.91C>T (p.R31C) alteration is located in exon 3 (coding exon 1) of the CERS4 gene. This alteration results from a C to T substitution at nucleotide position 91, causing the arginine (R) at amino acid position 31 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
