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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2023The c.694G>A (p.A232T) alteration is located in exon 8 (coding exon 8) of the SNF8 gene. This alteration results from a G to A substitution at nucleotide position 694, causing the alanine (A) at amino acid position 232 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
