Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.37G>A (p.A13T) alteration is located in exon 3 (coding exon 1) of the NRSN1 gene. This alteration results from a G to A substitution at nucleotide position 37, causing the alanine (A) at amino acid position 13 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
