Summary

Story summary

A case study reports that a patient with a heterozygous ATP6V0A4 variant developed distal renal tubular acidosis (dRTA) after taking clozapine, presenting in adulthood without sensorineural hearing loss.
The authors propose that clozapine triggered overt dRTA by increasing systemic acid load or causing direct renal injury.
The case underscores the need for more research on gene-drug interactions and personalized treatment strategies for patients with genetic predispositions.
