Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2023The c.617T>C (p.I206T) alteration is located in exon 3 (coding exon 3) of the EEFSEC gene. This alteration results from a T to C substitution at nucleotide position 617, causing the isoleucine (I) at amino acid position 206 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
