Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 14, 2024The c.1222C>T (p.R408C) alteration is located in exon 12 (coding exon 11) of the ARHGAP28 gene. This alteration results from a C to T substitution at nucleotide position 1222, causing the arginine (R) at amino acid position 408 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
