Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2022The c.1253T>C (p.F418S) alteration is located in exon 13 (coding exon 12) of the CCDC38 gene. This alteration results from a T to C substitution at nucleotide position 1253, causing the phenylalanine (F) at amino acid position 418 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
