Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 26, 2023The c.377C>T (p.T126M) alteration is located in exon 3 (coding exon 3) of the NIPSNAP3B gene. This alteration results from a C to T substitution at nucleotide position 377, causing the threonine (T) at amino acid position 126 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
