Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2022The c.800C>T (p.P267L) alteration is located in exon 8 (coding exon 8) of the CNPPD1 gene. This alteration results from a C to T substitution at nucleotide position 800, causing the proline (P) at amino acid position 267 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
