Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2024The c.488C>T (p.S163F) 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 488, causing the serine (S) at amino acid position 163 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
