The c.310G>A (p.D104N) alteration is located in exon 3 (coding exon 1) of the TCEAL6 gene. This alteration results from a G to A substitution at nucleotide position 310, causing the aspartic acid (D) at amino acid position 104 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
