Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2023The c.632C>T (p.S211F) alteration is located in exon 7 (coding exon 7) of the ARHGEF33 gene. This alteration results from a C to T substitution at nucleotide position 632, causing the serine (S) at amino acid position 211 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
