Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The c.460C>G (p.P154A) alteration is located in exon 3 (coding exon 2) of the NCAN gene. This alteration results from a C to G substitution at nucleotide position 460, causing the proline (P) at amino acid position 154 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
