Genes affected
ARFRP1 (HGNC:662): (ADP ribosylation factor related protein 1) The protein encoded by this gene is a membrane-associated GTP-ase which localizes to the plasma membrane and is related to the ADP-ribosylation factor (ARF) and ARF-like (ARL) proteins. This gene plays a role in membrane trafficking between the trans-Golgi network and endosomes. Alternatively spliced transcript variants encoding different isoforms have been identified.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2021The c.136A>G (p.K46E) alteration is located in exon 3 (coding exon 2) of the ARFRP1 gene. This alteration results from a A to G substitution at nucleotide position 136, causing the lysine (K) at amino acid position 46 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
