Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 12, 2021The c.460C>T (p.R154W) alteration is located in exon 4 (coding exon 4) of the CCDC136 gene. This alteration results from a C to T substitution at nucleotide position 460, causing the arginine (R) at amino acid position 154 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
