Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2024The c.139C>T (p.R47W) alteration is located in exon 2 (coding exon 2) of the CCDC90B gene. This alteration results from a C to T substitution at nucleotide position 139, causing the arginine (R) at amino acid position 47 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
