Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.3526C>T (p.P1176S) alteration is located in exon 16 (coding exon 15) of the ARHGAP20 gene. This alteration results from a C to T substitution at nucleotide position 3526, causing the proline (P) at amino acid position 1176 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
