Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2023The c.715C>T (p.L239F) alteration is located in exon 9 (coding exon 7) of the CCDC68 gene. This alteration results from a C to T substitution at nucleotide position 715, causing the leucine (L) at amino acid position 239 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
