Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2023The c.2008G>A (p.D670N) alteration is located in exon 13 (coding exon 13) of the SMG5 gene. This alteration results from a G to A substitution at nucleotide position 2008, causing the aspartic acid (D) at amino acid position 670 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
