Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 17, 2023The c.476A>G (p.N159S) 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 476, causing the asparagine (N) at amino acid position 159 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
