The c.905A>T (p.H302L) alteration is located in exon 8 (coding exon 8) of the AACS gene. This alteration results from a A to T substitution at nucleotide position 905, causing the histidine (H) at amino acid position 302 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
