The c.212A>G (p.K71R) alteration is located in exon 3 (coding exon 1) of the TCEAL6 gene. This alteration results from a A to G substitution at nucleotide position 212, causing the lysine (K) at amino acid position 71 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
