Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2024The c.491A>G (p.Q164R) alteration is located in exon 5 (coding exon 5) of the ARHGEF33 gene. This alteration results from a A to G substitution at nucleotide position 491, causing the glutamine (Q) at amino acid position 164 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
