Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2022The c.1421A>G (p.Y474C) alteration is located in exon 6 (coding exon 6) of the RNF219 gene. This alteration results from a A to G substitution at nucleotide position 1421, causing the tyrosine (Y) at amino acid position 474 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
