The c.2581C>G (p.L861V) alteration is located in exon 16 (coding exon 16) of the TBC1D9 gene. This alteration results from a C to G substitution at nucleotide position 2581, causing the leucine (L) at amino acid position 861 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
