Consequently, tissue samples containing both the pituitary adenoma component and the rhabdoid tumor component in the same slide were sent for next generation sequencing, revealing a MEN1 p. L39fs frameshift mutation, an MRE11 splice site mutation, homozygous CDKN2A/B deletion, and loss of proximal 22q. The gene discussed is CDKN2A; the disease is pituitary gland adenoma.
