Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 13, 2022The c.235A>G (p.K79E) alteration is located in exon 3 (coding exon 3) of the SAMSN1 gene. This alteration results from a A to G substitution at nucleotide position 235, causing the lysine (K) at amino acid position 79 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
