Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2023The c.661A>G (p.M221V) alteration is located in exon 6 (coding exon 5) of the PRRG4 gene. This alteration results from a A to G substitution at nucleotide position 661, causing the methionine (M) at amino acid position 221 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
