Genes affected

ARL6IP4 (HGNC:18076): (ADP ribosylation factor like GTPase 6 interacting protein 4) Enables identical protein binding activity. Predicted to be involved in RNA splicing and mRNA processing. Predicted to be located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ARL6IP4 links:

ABCB9 (HGNC:50): (ATP binding cassette subfamily B member 9) The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance as well as antigen presentation. This family member functions in the translocation of peptides from the cytosol into the lysosomal lumen. Alternative splicing of this gene results in distinct isoforms which are likely to have different substrate specificities. [provided by RefSeq, Jul 2011]

The c.460G>A (p.D154N) alteration is located in exon 2 (coding exon 2) of the ARL6IP4 gene. This alteration results from a G to A substitution at nucleotide position 460, causing the aspartic acid (D) at amino acid position 154 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
