The c.809T>C (p.M270T) alteration is located in exon 8 (coding exon 8) of the TCEA3 gene. This alteration results from a T to C substitution at nucleotide position 809, causing the methionine (M) at amino acid position 270 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
