Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2022The c.743C>T (p.S248L) alteration is located in exon 7 (coding exon 5) of the ECT2L gene. This alteration results from a C to T substitution at nucleotide position 743, causing the serine (S) at amino acid position 248 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
