Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.389C>T (p.T130M) alteration is located in exon 4 (coding exon 3) of the ITLN1 gene. This alteration results from a C to T substitution at nucleotide position 389, causing the threonine (T) at amino acid position 130 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
