Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 08, 2024The c.124G>A (p.E42K) alteration is located in exon 3 (coding exon 2) of the ARHGAP28 gene. This alteration results from a G to A substitution at nucleotide position 124, causing the glutamic acid (E) at amino acid position 42 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
