Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.859C>T (p.R287W) alteration is located in exon 8 (coding exon 6) of the ECT2L gene. This alteration results from a C to T substitution at nucleotide position 859, causing the arginine (R) at amino acid position 287 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
