Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2021The c.1304C>T (p.T435M) alteration is located in exon 13 (coding exon 12) of the ARHGAP28 gene. This alteration results from a C to T substitution at nucleotide position 1304, causing the threonine (T) at amino acid position 435 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
