Collection Method: clinical testing

The c.896G>T (p.C299F) alteration is located in exon 1 (coding exon 1) of the FOXD4L5 gene. This alteration results from a G to T substitution at nucleotide position 896, causing the cysteine (C) at amino acid position 299 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
