Elena Savva (Victorian Clinical Genetics Services)

Green List (high evidence)

Function: catalyzes the phosphorylation of the lipids that are essential for a variety of cellular processes including cilia formation and vesicle trafficking.

PMID: 31034465 - 3 unrelated families (5 patients) with cataracts, skeletal abnormalities, hearing loss, nephrocalcinosis, visual defects etc. Variants included a nonsense, canonical splice causing a large inframe deletion-insertion and intragenic CNV.
MRIs revealed multiple forntal and periventricular lacunar infarcts, lesions of white matter. No mention of MTS or cerebellar atrophy.
Functional assays on patents fibroblasts showed reduced accumulation of PI(3)P (a downstream target of this gene) at the base of cilia and reduced cilia length.
