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 Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BP7: Synonymous conserved (PhyloP=-4.28 with no splicing effect.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.664 is higher than 0.05.
