Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2024The c.100G>T (p.G34C) alteration is located in exon 1 (coding exon 1) of the NIPAL2 gene. This alteration results from a G to T substitution at nucleotide position 100, causing the glycine (G) at amino acid position 34 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
