Variant chrX-136344734-C-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_153834.4(ADGRG4):c.1028C>A(p.Thr343Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000174 in 1,207,333 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 10 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 12/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T343R) has been classified as Uncertain significance.

Genes affected

ADGRG4 (HGNC:18992): (adhesion G protein-coupled receptor G4) This gene encodes a G-protein coupled receptor belonging to a large family of diverse integral membrane proteins that participate in various physiological functions. Members of this superfamily are characterized by a signature 7-transmembrane domain motif. The ligand for this family member is unknown, and it is therefore an orphan receptor. This receptor is known to be expressed in normal enterochromaffin cells and in gastrointestinal neuroendocrine carcinoma cells, and it is therefore considered to be a novel biomarker or target for immunotherapy.

The c.1028C>A (p.T343K) alteration is located in exon 6 (coding exon 3) of the ADGRG4 gene. This alteration results from a C to A substitution at nucleotide position 1028, causing the threonine (T) at amino acid position 343 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
