Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2022The c.2071C>T (p.R691C) alteration is located in exon 19 (coding exon 19) of the NSF gene. This alteration results from a C to T substitution at nucleotide position 2071, causing the arginine (R) at amino acid position 691 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
