Green List (high evidence)

Comment on list classification: Rating Amber but should be promoted to Green at the next GMS panel update (added 'for-review tag). Two unrelated cases exhibiting a consistent phenotype, supported by functional characterisation of harboured variants and concordant animal models.

- PMID: 33106379 (2020) - Distinct homozygous variants in PRKG2 identified in two unrelated individuals, both with a skeletal dysplasia associated with severe short stature due to acromesomelic limb shortening, brachydactyly, mild to moderate platyspondyly and progressively increasing metaphyseal alterations of the long bones.

Functional studies showed both variants result in NMD and disrupt the downstream MAPK signalling pathway in response to FGF2. The role of cGKII, encoded by PRKG2, in skeletal growth has been established in several animal models (references provided in paper).
