not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 02, 2023The c.1342G>A (p.G448R) alteration is located in exon 4 (coding exon 4) of the EMILIN3 gene. This alteration results from a G to A substitution at nucleotide position 1342, causing the glycine (G) at amino acid position 448 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
