Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2024The c.1320A>C (p.K440N) alteration is located in exon 6 (coding exon 6) of the RNF219 gene. This alteration results from a A to C substitution at nucleotide position 1320, causing the lysine (K) at amino acid position 440 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
