Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 09, 2021The c.536T>C (p.L179P) alteration is located in exon 1 (coding exon 1) of the CCDC54 gene. This alteration results from a T to C substitution at nucleotide position 536, causing the leucine (L) at amino acid position 179 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
