The c.5854G>A (p.V1952I) alteration is located in exon 33 (coding exon 33) of the AHCTF1 gene. This alteration results from a G to A substitution at nucleotide position 5854, causing the valine (V) at amino acid position 1952 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
