Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 13, 2023The c.479G>A (p.G160D) alteration is located in exon 5 (coding exon 5) of the ITLN2 gene. This alteration results from a G to A substitution at nucleotide position 479, causing the glycine (G) at amino acid position 160 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
