Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.788C>G (p.S263C) alteration is located in exon 3 (coding exon 2) of the CCDC181 gene. This alteration results from a C to G substitution at nucleotide position 788, causing the serine (S) at amino acid position 263 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
