Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 11, 2022The c.349G>A (p.A117T) alteration is located in exon 3 (coding exon 3) of the NIPAL2 gene. This alteration results from a G to A substitution at nucleotide position 349, causing the alanine (A) at amino acid position 117 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
