Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2021The c.709C>T (p.R237C) alteration is located in exon 7 (coding exon 6) of the CCDC63 gene. This alteration results from a C to T substitution at nucleotide position 709, causing the arginine (R) at amino acid position 237 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
