Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 11, 2022The c.718G>C (p.D240H) alteration is located in exon 7 (coding exon 7) of the ARHGEF33 gene. This alteration results from a G to C substitution at nucleotide position 718, causing the aspartic acid (D) at amino acid position 240 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
