Ambry Genetics

Dec 05, 2022

The c.233C>T (p.P78L) alteration is located in exon 2 (coding exon 2) of the CERS6 gene. This alteration results from a C to T substitution at nucleotide position 233, causing the proline (P) at amino acid position 78 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
