Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.493C>T (p.R165C) alteration is located in exon 5 (coding exon 5) of the FNDC1 gene. This alteration results from a C to T substitution at nucleotide position 493, causing the arginine (R) at amino acid position 165 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
