Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.1072A>G (p.N358D) alteration is located in exon 8 (coding exon 8) of the SAMSN1 gene. This alteration results from a A to G substitution at nucleotide position 1072, causing the asparagine (N) at amino acid position 358 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
