Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 13, 2021The c.512C>T (p.T171M) alteration is located in exon 5 (coding exon 4) of the ITLN1 gene. This alteration results from a C to T substitution at nucleotide position 512, causing the threonine (T) at amino acid position 171 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
