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 17, 2022

The c.271G>C (p.D91H) alteration is located in exon 3 (coding exon 2) of the RALBP1 gene. This alteration results from a G to C substitution at nucleotide position 271, causing the aspartic acid (D) at amino acid position 91 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
