Genes affected
TTC36 (HGNC:33708): (tetratricopeptide repeat domain 36) The protein encoded by this gene has three tetratricopeptide repeats and is a chaperone for heat shock protein 70. The encoded protein may function as a tumor suppressor in hepatocellular carcinoma (HCC) since it promotes apoptosis but is downregulated in HCC. [provided by RefSeq, Sep 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2022The c.556C>T (p.R186C) alteration is located in exon 3 (coding exon 3) of the TTC36 gene. This alteration results from a C to T substitution at nucleotide position 556, causing the arginine (R) at amino acid position 186 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
