Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2023The c.1162C>T (p.R388W) alteration is located in exon 8 (coding exon 8) of the RABEP2 gene. This alteration results from a C to T substitution at nucleotide position 1162, causing the arginine (R) at amino acid position 388 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
