Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2022The c.67A>T (p.I23F) alteration is located in exon 2 (coding exon 2) of the ARHGEF33 gene. This alteration results from a A to T substitution at nucleotide position 67, causing the isoleucine (I) at amino acid position 23 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
