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]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.1257T>A (p.S419R) alteration is located in exon 9 (coding exon 9) of the CCDC6 gene. This alteration results from a T to A substitution at nucleotide position 1257, causing the serine (S) at amino acid position 419 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
