Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 10, 2022The c.2524G>A (p.G842S) alteration is located in exon 22 (coding exon 21) of the EXD3 gene. This alteration results from a G to A substitution at nucleotide position 2524, causing the glycine (G) at amino acid position 842 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
