Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2024The c.156T>A (p.D52E) alteration is located in exon 3 (coding exon 3) of the CCDC138 gene. This alteration results from a T to A substitution at nucleotide position 156, causing the aspartic acid (D) at amino acid position 52 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
