Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2024The c.903T>A (p.D301E) alteration is located in exon 8 (coding exon 8) of the ITLN2 gene. This alteration results from a T to A substitution at nucleotide position 903, causing the aspartic acid (D) at amino acid position 301 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
