Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2024The c.1579C>G (p.P527A) alteration is located in exon 1 (coding exon 1) of the CCT8L2 gene. This alteration results from a C to G substitution at nucleotide position 1579, causing the proline (P) at amino acid position 527 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
