Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2022The c.994A>C (p.T332P) alteration is located in exon 3 (coding exon 2) of the CCDC181 gene. This alteration results from a A to C substitution at nucleotide position 994, causing the threonine (T) at amino acid position 332 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
