Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 11, 2024The c.379T>C (p.C127R) alteration is located in exon 1 (coding exon 1) of the FAM26E gene. This alteration results from a T to C substitution at nucleotide position 379, causing the cysteine (C) at amino acid position 127 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
