Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2023The c.580G>A (p.E194K) alteration is located in exon 7 (coding exon 7) of the CCDC90B gene. This alteration results from a G to A substitution at nucleotide position 580, causing the glutamic acid (E) at amino acid position 194 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
