Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2023The c.245A>G (p.K82R) alteration is located in exon 2 (coding exon 2) of the SNED1 gene. This alteration results from a A to G substitution at nucleotide position 245, causing the lysine (K) at amino acid position 82 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
