Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2021The c.872G>A (p.R291Q) alteration is located in exon 4 (coding exon 4) of the CPPED1 gene. This alteration results from a G to A substitution at nucleotide position 872, causing the arginine (R) at amino acid position 291 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
