The c.616G>A (p.V206I) alteration is located in exon 5 (coding exon 4) of the TBCEL gene. This alteration results from a G to A substitution at nucleotide position 616, causing the valine (V) at amino acid position 206 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
