Genes affected
TSKU (HGNC:28850): (tsukushi, small leucine rich proteoglycan) Predicted to enable transforming growth factor beta binding activity. Predicted to be involved in several processes, including animal organ development; cholesterol efflux; and cholesterol homeostasis. Predicted to act upstream of or within several processes, including ciliary body morphogenesis; negative regulation of Wnt signaling pathway; and telencephalon development. Predicted to be located in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2022The c.242C>G (p.P81R) alteration is located in exon 2 (coding exon 1) of the TSKU gene. This alteration results from a C to G substitution at nucleotide position 242, causing the proline (P) at amino acid position 81 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
