Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2021The c.1046G>C (p.R349T) alteration is located in exon 11 (coding exon 10) of the ARHGAP28 gene. This alteration results from a G to C substitution at nucleotide position 1046, causing the arginine (R) at amino acid position 349 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
