Collection Method: clinical testing

The c.329T>C (p.F110S) alteration is located in exon 4 (coding exon 3) of the TCEANC2 gene. This alteration results from a T to C substitution at nucleotide position 329, causing the phenylalanine (F) at amino acid position 110 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
