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.

The c.1714T>A (p.L572M) alteration is located in exon 11 (coding exon 10) of the JADE1 gene. This alteration results from a T to A substitution at nucleotide position 1714, causing the leucine (L) at amino acid position 572 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
