Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2021The c.77C>T (p.A26V) alteration is located in exon 1 (coding exon 1) of the NEMP2 gene. This alteration results from a C to T substitution at nucleotide position 77, causing the alanine (A) at amino acid position 26 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
