Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2023The c.355T>C (p.S119P) alteration is located in exon 6 (coding exon 4) of the CCDC68 gene. This alteration results from a T to C substitution at nucleotide position 355, causing the serine (S) at amino acid position 119 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
