Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 26, 2024The c.368C>T (p.T123I) alteration is located in exon 5 (coding exon 5) of the ARHGEF33 gene. This alteration results from a C to T substitution at nucleotide position 368, causing the threonine (T) at amino acid position 123 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
