Genes affected

VPS28 (HGNC:18178): (VPS28 subunit of ESCRT-I) This gene encodes a protein subunit of the ESCRT-I complex (endosomal complexes required for transport), which functions in the transport and sorting of proteins into subcellular vesicles. This complex can also be hijacked to facilitate the budding of enveloped viruses from the cell membrane. Alternative splicing results in multiple transcript variants encoding different isoforms.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.290G>A (p.R97H) alteration is located in exon 6 (coding exon 5) of the VPS28 gene. This alteration results from a G to A substitution at nucleotide position 290, causing the arginine (R) at amino acid position 97 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
