Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.478A>G (p.N160D) alteration is located in exon 5 (coding exon 5) of the CNPPD1 gene. This alteration results from a A to G substitution at nucleotide position 478, causing the asparagine (N) at amino acid position 160 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
