The c.733A>G (p.I245V) alteration is located in exon 6 (coding exon 5) of the TBCEL gene. This alteration results from a A to G substitution at nucleotide position 733, causing the isoleucine (I) at amino acid position 245 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
