Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 17, 2023The c.632C>T (p.S211L) alteration is located in exon 5 (coding exon 5) of the CCDC66 gene. This alteration results from a C to T substitution at nucleotide position 632, causing the serine (S) at amino acid position 211 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
