Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 10, 2023The c.169G>T (p.A57S) alteration is located in exon 5 (coding exon 2) of the CCDC36 gene. This alteration results from a G to T substitution at nucleotide position 169, causing the alanine (A) at amino acid position 57 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
