Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2024The c.406C>T (p.R136C) alteration is located in exon 3 (coding exon 2) of the CCDC51 gene. This alteration results from a C to T substitution at nucleotide position 406, causing the arginine (R) at amino acid position 136 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
