Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2023The c.181T>A (p.C61S) alteration is located in exon 3 (coding exon 2) of the CNFN gene. This alteration results from a T to A substitution at nucleotide position 181, causing the cysteine (C) at amino acid position 61 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
