Summary

CHARGE association can include hypogonadotrophic hypogonadism. This case highlights a rare instance of pituitary/hypothalamic hypoadrenalism in CHARGE syndrome, alongside 22q11 deletion overlap and cervical vertebral anomalies.

Area of Science:

  • Endocrinology
  • Genetics
  • Pediatric Medicine

Background:

  • Hypogonadotrophic hypogonadism is a recognized feature of CHARGE association.
  • Previous literature has not extensively documented broader pituitary dysfunction in CHARGE syndrome.

Observation:

  • A patient with CHARGE association presented with hypogonadotrophic hypogonadism.
  • Further evaluation revealed hypoadrenalism originating from the pituitary/hypothalamic axis.
  • The patient also exhibited features overlapping with 22q11 deletion syndrome and a unique cervical vertebral abnormality.

Findings:

  • This case expands the known spectrum of endocrine dysfunction in CHARGE association.
  • It demonstrates pituitary/hypothalamic hypoadrenalism as a potential, albeit rare, manifestation.

Related Experiment Videos

  • The co-occurrence of CHARGE, 22q11 deletion features, and cervical vertebral anomalies is noteworthy.

    • Implications:

    • Clinicians should consider comprehensive pituitary function testing in patients with CHARGE association.
    • This finding may refine diagnostic criteria and management strategies for CHARGE syndrome.
    • Further research is warranted to understand the genetic and clinical correlations between these overlapping syndromes.
