Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2023The c.103G>T (p.D35Y) alteration is located in exon 3 (coding exon 2) of the ARHGAP28 gene. This alteration results from a G to T substitution at nucleotide position 103, causing the aspartic acid (D) at amino acid position 35 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
