Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.440C>T (p.A147V) alteration is located in exon 4 (coding exon 4) of the NWD2 gene. This alteration results from a C to T substitution at nucleotide position 440, causing the alanine (A) at amino acid position 147 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
