Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2021The c.658G>A (p.V220I) alteration is located in exon 6 (coding exon 6) of the NEMP2 gene. This alteration results from a G to A substitution at nucleotide position 658, causing the valine (V) at amino acid position 220 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
