Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.485C>T (p.A162V) alteration is located in exon 7 (coding exon 6) of the NMRK2 gene. This alteration results from a C to T substitution at nucleotide position 485, causing the alanine (A) at amino acid position 162 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
