The c.122C>T (p.S41F) alteration is located in exon 2 (coding exon 1) of the TBCEL gene. This alteration results from a C to T substitution at nucleotide position 122, causing the serine (S) at amino acid position 41 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
