Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.685T>C (p.F229L) alteration is located in exon 5 (coding exon 5) of the FNDC7 gene. This alteration results from a T to C substitution at nucleotide position 685, causing the phenylalanine (F) at amino acid position 229 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
