Genes affected
SNF8 (HGNC:17028): (SNF8 subunit of ESCRT-II) The protein encoded by this gene is a component of the endosomal sorting complex required for transport II (ESCRT-II), which regulates the movement of ubiquitinylated transmembrane proteins to the lysosome for degradation. This complex also interacts with the RNA polymerase II elongation factor (ELL) to overcome the repressive effects of ELL on RNA polymerase II activity. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2015]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 3 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 1.1333 (below the threshold of 3.09). Trascript score misZ: 1.3894 (below the threshold of 3.09). GenCC associations: The gene is linked to neurodevelopmental disorder plus optic atrophy, complex neurodevelopmental disorder.
BP4
Computational evidence support a benign effect (MetaRNN=0.03630531).
BS2
High Homozygotes in GnomAdExome4 at 4 AR gene
