Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2021The c.743A>G (p.D248G) alteration is located in exon 7 (coding exon 7) of the CCDC138 gene. This alteration results from a A to G substitution at nucleotide position 743, causing the aspartic acid (D) at amino acid position 248 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
