Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 03, 2022The c.258T>A (p.H86Q) alteration is located in exon 2 (coding exon 2) of the NIPSNAP3B gene. This alteration results from a T to A substitution at nucleotide position 258, causing the histidine (H) at amino acid position 86 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
