Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 06, 2022The c.419C>T (p.A140V) alteration is located in exon 4 (coding exon 4) of the ITLN2 gene. This alteration results from a C to T substitution at nucleotide position 419, causing the alanine (A) at amino acid position 140 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
