Description

The c.1387A>G (p.T463A) alteration is located in exon 13 (coding exon 13) of the TTC8 gene. This alteration results from a A to G substitution at nucleotide position 1387, causing the threonine (T) at amino acid position 463 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
