The c.781G>A (p.A261T) alteration is located in exon 4 (coding exon 3) of the ANGPTL6 gene. This alteration results from a G to A substitution at nucleotide position 781, causing the alanine (A) at amino acid position 261 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
