Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2023The c.338C>G (p.A113G) alteration is located in exon 2 (coding exon 2) of the SNED1 gene. This alteration results from a C to G substitution at nucleotide position 338, causing the alanine (A) at amino acid position 113 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
