Genes affected

RALBP1 (HGNC:9841): (ralA binding protein 1) RALBP1 plays a role in receptor-mediated endocytosis and is a downstream effector of the small GTP-binding protein RAL (see RALA; MIM 179550). Small G proteins, such as RAL, have GDP-bound inactive and GTP-bound active forms, which shift from the inactive to the active state through the action of RALGDS (MIM 601619), which in turn is activated by RAS (see HRAS; MIM 190020) (summary by Feig, 2003 [PubMed 12888294]).[supplied by OMIM, Nov 2010]

Ambry Genetics

Aug 08, 2022

The c.964A>G (p.I322V) alteration is located in exon 4 (coding exon 3) of the RALBP1 gene. This alteration results from a A to G substitution at nucleotide position 964, causing the isoleucine (I) at amino acid position 322 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
