Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 18, 2021The c.2182G>A (p.D728N) alteration is located in exon 19 (coding exon 18) of the CCDC178 gene. This alteration results from a G to A substitution at nucleotide position 2182, causing the aspartic acid (D) at amino acid position 728 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
