Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 20, 2023The c.466G>C (p.E156Q) alteration is located in exon 6 (coding exon 6) of the ARL8A gene. This alteration results from a G to C substitution at nucleotide position 466, causing the glutamic acid (E) at amino acid position 156 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
