Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_003492.3(TMEM187):​c.209C>G​(p.Ser70Trp) 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. 14/20 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. S70L) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 25)
• Consequence: TMEM187 NM_003492.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 1.78

Genes affected

TMEM187 (HGNC:13705): (transmembrane protein 187) This gene consists of two exons and encodes a multi-pass membrane protein. An alternatively spliced transcript variant encoding the same protein has been found, but its biological validity is not determined. [provided by RefSeq, May 2010]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.11855957).
