Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2024The c.232G>A (p.G78S) alteration is located in exon 4 (coding exon 3) of the ITLN1 gene. This alteration results from a G to A substitution at nucleotide position 232, causing the glycine (G) at amino acid position 78 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
