Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2022The c.41G>T (p.R14L) alteration is located in exon 2 (coding exon 1) of the FNDC4 gene. This alteration results from a G to T substitution at nucleotide position 41, causing the arginine (R) at amino acid position 14 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
