Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 24, 2024The c.781T>C (p.F261L) alteration is located in exon 8 (coding exon 8) of the TCEA1 gene. This alteration results from a T to C substitution at nucleotide position 781, causing the phenylalanine (F) at amino acid position 261 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
