Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.841A>G (p.N281D) alteration is located in exon 2 (coding exon 1) of the CCSER2 gene. This alteration results from a A to G substitution at nucleotide position 841, causing the asparagine (N) at amino acid position 281 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
