The c.682A>G (p.T228A) alteration is located in exon 9 (coding exon 8) of the BTBD16 gene. This alteration results from a A to G substitution at nucleotide position 682, causing the threonine (T) at amino acid position 228 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
