The c.706G>T (p.V236L) alteration is located in exon 7 (coding exon 7) of the AACS gene. This alteration results from a G to T substitution at nucleotide position 706, causing the valine (V) at amino acid position 236 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
