Genes affected

RIPOR1 (HGNC:25836): (RHO family interacting cell polarization regulator 1) Enables 14-3-3 protein binding activity. Involved in several processes, including establishment of Golgi localization; negative regulation of Rho guanyl-nucleotide exchange factor activity; and negative regulation of Rho protein signal transduction. Located in Golgi apparatus; cell leading edge; and membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.542G>A (p.R181H) alteration is located in exon 7 (coding exon 7) of the FAM65A gene. This alteration results from a G to A substitution at nucleotide position 542, causing the arginine (R) at amino acid position 181 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
