The c.431C>T (p.T144I) alteration is located in exon 6 (coding exon 5) of the TTC12 gene. This alteration results from a C to T substitution at nucleotide position 431, causing the threonine (T) at amino acid position 144 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
