Genes affected
RIC1 (HGNC:17686): (RIC1 homolog, RAB6A GEF complex partner 1) Enables guanyl-nucleotide exchange factor activity and small GTPase binding activity. Involved in several processes, including positive regulation of GTPase activity; regulation of extracellular matrix constituent secretion; and retrograde transport, endosome to Golgi. Located in cytosol and membrane. Part of Ric1-Rgp1 guanyl-nucleotide exchange factor complex. [provided by Alliance of Genome Resources, Apr 2022]
ERMP1 (HGNC:23703): (endoplasmic reticulum metallopeptidase 1) Predicted to enable metal ion binding activity and metalloexopeptidase activity. Involved in cellular response to oxidative stress. Acts upstream of or within endoplasmic reticulum unfolded protein response. Located in membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.1549G>A (p.A517T) alteration is located in exon 14 (coding exon 14) of the RIC1 gene. This alteration results from a G to A substitution at nucleotide position 1549, causing the alanine (A) at amino acid position 517 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
