Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.296C>T (p.P99L) alteration is located in exon 3 (coding exon 3) of the CPPED1 gene. This alteration results from a C to T substitution at nucleotide position 296, causing the proline (P) at amino acid position 99 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
