Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 12, 2024The c.807C>G (p.C269W) alteration is located in exon 4 (coding exon 4) of the CPPED1 gene. This alteration results from a C to G substitution at nucleotide position 807, causing the cysteine (C) at amino acid position 269 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
