Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2022The c.631G>C (p.V211L) alteration is located in exon 7 (coding exon 6) of the ARHGAP28 gene. This alteration results from a G to C substitution at nucleotide position 631, causing the valine (V) at amino acid position 211 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
