Congenital and iatrogenic laryngeal and vocal abnormalities in patients with 22q11.2 deletion

Out of 109 patients with 22q11.2 deletion, 18% displayed a laryngeal abnormality and 17% had abnormal vocal quality. This suggests that voice and vocal fold abnormalities are important to consider in this population. Distinguishing between speech and voice abnormalities in patients with 22q11.2 deletion can help ensure appropriate intervention.
