Collection Method: clinical testing

The c.71C>T (p.S24F) alteration is located in exon 3 (coding exon 2) of the TMEM14B gene. This alteration results from a C to T substitution at nucleotide position 71, causing the serine (S) at amino acid position 24 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
