Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2024The c.568G>A (p.V190I) alteration is located in exon 5 (coding exon 5) of the PRRC2B gene. This alteration results from a G to A substitution at nucleotide position 568, causing the valine (V) at amino acid position 190 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
