Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 01, 2023The c.566T>C (p.M189T) alteration is located in exon 7 (coding exon 7) of the CCDC90B gene. This alteration results from a T to C substitution at nucleotide position 566, causing the methionine (M) at amino acid position 189 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
