Phenotypes

Mouse phenotype:
preweaning lethality, complete penetrance, abnormal gait, abnormal locomotor activation, abnormal forelimb morphology, cornea vascularization, increased startle reflex, increased mean corpuscular volume, limb grasping, decreased circulating amylase level, abnormal bone mineralization, abnormal response to new environment, increased circulating iron level, increased lean body mass
Human ciliopathy phenotype:
Spinocerebellar ataxia type 41

Subcellular localization

cilia associated gene

Functional category

  • Ciliary assembly/disassembly
  • Signaling (Hedgehog, GPCRs, ion channels)
  • Cardiac & muscle development
  • Transcription regulation

Function

Mutations in the TRPC3 gene cause Spinocerebellar Ataxia (PMID: 25477146).

Model organism evidence

Xenopus (1 reference)

Here, we show that Shh enhances Ca2+ activity at the neural cell primary cilium of developing Xenopus laevis embryos through Ca2+ influx via transient receptor potential cation channel subfamily C member 3 (TRPC3) and release from intracellular stores in a developmental stage-dependent manner.
