Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 25, 2023The c.917G>A (p.R306K) alteration is located in exon 8 (coding exon 8) of the ARHGEF33 gene. This alteration results from a G to A substitution at nucleotide position 917, causing the arginine (R) at amino acid position 306 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
