Genes affected
VIT (HGNC:12697): (vitrin) This gene encodes an extracellular matrix (ECM) protein. The protein may be associated with cell adhesion and migration. High levels of expression of the protein in specific parts of the brain suggest its likely role in neural development. [provided by RefSeq, Jun 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 17, 2023The c.587C>G (p.T196S) alteration is located in exon 7 (coding exon 6) of the VIT gene. This alteration results from a C to G substitution at nucleotide position 587, causing the threonine (T) at amino acid position 196 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
