Collection Method: clinical testing

The c.1342C>T (p.R448W) alteration is located in exon 5 (coding exon 5) of the FAM83E gene. This alteration results from a C to T substitution at nucleotide position 1342, causing the arginine (R) at amino acid position 448 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
