Genes affected
ARL4D (HGNC:656): (ADP ribosylation factor like GTPase 4D) ADP-ribosylation factor 4D is a member of the ADP-ribosylation factor family of GTP-binding proteins. ARL4D is closely similar to ARL4A and ARL4C and each has a nuclear localization signal and an unusually high guanine nucleotide exchange rate. This protein may play a role in membrane-associated intracellular trafficking. [provided by RefSeq, Jul 2021]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2023The c.138T>G (p.F46L) alteration is located in exon 2 (coding exon 1) of the ARL4D gene. This alteration results from a T to G substitution at nucleotide position 138, causing the phenylalanine (F) at amino acid position 46 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
