Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2022The c.946G>A (p.G316S) alteration is located in exon 1 (coding exon 1) of the CCDC54 gene. This alteration results from a G to A substitution at nucleotide position 946, causing the glycine (G) at amino acid position 316 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
