Collection Method: clinical testing

The c.146A>T (p.H49L) alteration is located in exon 2 (coding exon 2) of the ATP9B gene. This alteration results from a A to T substitution at nucleotide position 146, causing the histidine (H) at amino acid position 49 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
