The c.435G>T (p.M145I) alteration is located in exon 4 (coding exon 3) of the TBCEL gene. This alteration results from a G to T substitution at nucleotide position 435, causing the methionine (M) at amino acid position 145 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
