Genes affected

ARRDC1 (HGNC:28633): (arrestin domain containing 1) Enables several functions, including arrestin family protein binding activity; ubiquitin ligase-substrate adaptor activity; and ubiquitin protein ligase binding activity. Involved in several processes, including cellular protein metabolic process; extracellular vesicle biogenesis; and negative regulation of Notch signaling pathway. Located in cytoplasmic vesicle; extracellular vesicle; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.101C>T (p.A34V) alteration is located in exon 1 (coding exon 1) of the ARRDC1 gene. This alteration results from a C to T substitution at nucleotide position 101, causing the alanine (A) at amino acid position 34 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
