The c.83G>C (p.G28A) alteration is located in exon 3 (coding exon 1) of the TCEAL6 gene. This alteration results from a G to C substitution at nucleotide position 83, causing the glycine (G) at amino acid position 28 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
