Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2024The c.1334C>T (p.S445F) alteration is located in exon 17 (coding exon 17) of the CCDC93 gene. This alteration results from a C to T substitution at nucleotide position 1334, causing the serine (S) at amino acid position 445 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
