The c.548T>G (p.V183G) alteration is located in exon 5 (coding exon 5) of the TTC17 gene. This alteration results from a T to G substitution at nucleotide position 548, causing the valine (V) at amino acid position 183 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
