Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_020893.6(CCDC180):​c.2435C>T​(p.Ser812Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S812C) has been classified as Benign.

Genes affected

CCDC180 (HGNC:29303): (coiled-coil domain containing 180) The protein encoded by this gene contains a coiled-coil domain. Alternative splicing results in multiple transcript variants encoding different isoforms. A single nucleotide polymorphism (SNP) in this gene has been associated with increased susceptibility to Behcet's Disease (PMID: 19442274). [provided by RefSeq, Dec 2016]

SUGT1P4-STRA6LP-CCDC180 (HGNC:53835): (SUGT1P4-STRA6LP-CCDC180 readthrough) This locus represents a set of read-through transcripts spanning an upstream pseudogene (GeneID:100499484) extending into a downstream protein-coding locus (GeneID:100499483). All of the read-through transcripts are candidates for nonsense-mediated decay (NMD), so they are not thought to express a protein. [provided by RefSeq, Aug 2010]

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.09076995).
