Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 12, 2024The c.1085A>T (p.E362V) alteration is located in exon 8 (coding exon 8) of the CCDC74B gene. This alteration results from a A to T substitution at nucleotide position 1085, causing the glutamic acid (E) at amino acid position 362 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
