The c.1069G>A (p.A357T) alteration is located in exon 9 (coding exon 8) of the KATNAL1 gene. This alteration results from a G to A substitution at nucleotide position 1069, causing the alanine (A) at amino acid position 357 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
