Congenital hypothyroidism v0.48 TRPC4AP Chris Richmond gene: TRPC4AP was added
gene: TRPC4AP was added to Congenital hypothyroidism. Sources: Expert Review,Literature
Mode of inheritance for gene: TRPC4AP was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted

Phenotypes for gene: TRPC4AP were set to Thyroid hypoplasia
Review for gene: TRPC4AP was set to AMBER
Added comment: De novo TRPC4AP variant has been identified on WES in a child with thyroid dyshormonogenesis. Next, 179 patients with CHTD sequenced using a panel of target genes identifying four variants in TRPC4AP. During development, Choukair et al. showed that Trpc4ap is expressed in the brain, the thyroid bud, and the kidney of the African clawed frog (Xenopus laevis). This team showed that disabling Trpc4ap in the African clawed frog leads to thyroid hypoplasia during development. It was also shown that TRPC4AP interacted with IKBKG which activates the NF-κB signaling pathway and regulates the genes involved in the growth and survival of thyrocytes. Furthermore, the NF-kB would control the expression of NKX2-1, PAX8, TPO, NIS, and TG.18 The authors conclude that TRPC4AP would be a new candidate gene for TDs.

Insufficient clinical cases for green. Candidate gene. Propose amber.
