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 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.833

The c.494A>T (p.Q165L) alteration is located in exon 3 (coding exon 3) of the CCDC6 gene. This alteration results from a A to T substitution at nucleotide position 494, causing the glutamine (Q) at amino acid position 165 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
