Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.880G>A (p.V294M) alteration is located in exon 9 (coding exon 9) of the NPRL2 gene. This alteration results from a G to A substitution at nucleotide position 880, causing the valine (V) at amino acid position 294 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
