Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_199320.4(JADE1):​c.1789C>G​(p.Arg597Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R597Q) has been classified as Uncertain significance.

Genes affected

JADE1 (HGNC:30027): (jade family PHD finger 1) Enables transcription coactivator activity. Involved in histone acetylation and negative regulation of canonical Wnt signaling pathway. Acts upstream of or within negative regulation of G1/S transition of mitotic cell cycle. Located in several cellular components, including ciliary basal body; cytosol; and nuclear speck. Part of histone acetyltransferase complex. [provided by Alliance of Genome Resources, Apr 2022]

SCLT1 (HGNC:26406): (sodium channel and clathrin linker 1) This gene encodes an adaptor protein. Studies of a related gene in rat suggest that the encoded protein functions to link clathrin to the sodium channel protein type 10 subunit alpha protein. The encoded protein has also been identified as a component of distal appendages of centrioles that is necessary for ciliogenesis. Alternative splicing results in multiple transcript variants.
