Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2024The c.670T>G (p.F224V) alteration is located in exon 2 (coding exon 1) of the CGN gene. This alteration results from a T to G substitution at nucleotide position 670, causing the phenylalanine (F) at amino acid position 224 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
