Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.362T>C (p.M121T) alteration is located in exon 4 (coding exon 4) of the TFPT gene. This alteration results from a T to C substitution at nucleotide position 362, causing the methionine (M) at amino acid position 121 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
