Ambry Genetics

Jul 19, 2022

The c.628C>T (p.L210F) alteration is located in exon 5 (coding exon 3) of the EXD2 gene. This alteration results from a C to T substitution at nucleotide position 628, causing the leucine (L) at amino acid position 210 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
