Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.176A>T (p.D59V) alteration is located in exon 3 (coding exon 3) of the CCDC138 gene. This alteration results from a A to T substitution at nucleotide position 176, causing the aspartic acid (D) at amino acid position 59 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
