Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2022The c.13G>A (p.V5M) alteration is located in exon 1 (coding exon 1) of the SMG8 gene. This alteration results from a G to A substitution at nucleotide position 13, causing the valine (V) at amino acid position 5 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
