Collection Method: clinical testing

The c.391C>T (p.H131Y) alteration is located in exon 2 (coding exon 2) of the ACOT6 gene. This alteration results from a C to T substitution at nucleotide position 391, causing the histidine (H) at amino acid position 131 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
