Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.50C>G (p.T17S) alteration is located in exon 2 (coding exon 1) of the CNPY2 gene. This alteration results from a C to G substitution at nucleotide position 50, causing the threonine (T) at amino acid position 17 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
