Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2021The c.644C>T (p.P215L) alteration is located in exon 7 (coding exon 7) of the CNPPD1 gene. This alteration results from a C to T substitution at nucleotide position 644, causing the proline (P) at amino acid position 215 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
