Genes affected

KITLG (HGNC:6343): (KIT ligand) This gene encodes the ligand of the tyrosine-kinase receptor encoded by the KIT locus. This ligand is a pleiotropic factor that acts in utero in germ cell and neural cell development, and hematopoiesis, all believed to reflect a role in cell migration. In adults, it functions pleiotropically, while mostly noted for its continued requirement in hematopoiesis. Two transcript variants encoding different isoforms have been found for this gene.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 210 of the KITLG protein (p.Asp210Gly). This variant is present in population databases (rs373521411, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with KITLG-related conditions. ClinVar contains an entry for this variant (Variation ID: 1325956). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt KITLG protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.629A>G (p.D210G) alteration is located in exon 7 (coding exon 7) of the KITLG gene. This alteration results from a A to G substitution at nucleotide position 629, causing the aspartic acid (D) at amino acid position 210 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
