Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 05, 2022The c.769C>T (p.R257W) alteration is located in exon 4 (coding exon 3) of the ARHGEF16 gene. This alteration results from a C to T substitution at nucleotide position 769, causing the arginine (R) at amino acid position 257 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
