Genes affected
CCDC6 (HGNC:18782): (coiled-coil domain containing 6) This gene encodes a coiled-coil domain-containing protein. The encoded protein is ubiquitously expressed and may function as a tumor suppressor. A chromosomal rearrangement resulting in the expression of a fusion gene containing a portion of this gene and the intracellular kinase-encoding domain of the ret proto-oncogene is the cause of thyroid papillary carcinoma.[provided by RefSeq, Sep 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 01, 2024The c.822G>T (p.K274N) alteration is located in exon 5 (coding exon 5) of the CCDC6 gene. This alteration results from a G to T substitution at nucleotide position 822, causing the lysine (K) at amino acid position 274 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
