Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2023The c.516T>A (p.H172Q) alteration is located in exon 5 (coding exon 5) of the ITLN2 gene. This alteration results from a T to A substitution at nucleotide position 516, causing the histidine (H) at amino acid position 172 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
