Collection Method: clinical testing

The c.209C>T (p.S70F) alteration is located in exon 2 (coding exon 1) of the LCE3E gene. This alteration results from a C to T substitution at nucleotide position 209, causing the serine (S) at amino acid position 70 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
