Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2024The c.538G>C (p.E180Q) alteration is located in exon 9 (coding exon 6) of the CCDC36 gene. This alteration results from a G to C substitution at nucleotide position 538, causing the glutamic acid (E) at amino acid position 180 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
