Ambry Genetics

Mar 18, 2024

The c.175T>A (p.F59I) alteration is located in exon 4 (coding exon 2) of the CERS4 gene. This alteration results from a T to A substitution at nucleotide position 175, causing the phenylalanine (F) at amino acid position 59 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
