Variant 6-47710807-T-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The ENST00000283303.3(ADGRF4):c.221T>C(p.Ile74Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000582 in 1,613,830 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. I74V) has been classified as Uncertain significance.

Genes affected

ADGRF4 (HGNC:19011): (adhesion G protein-coupled receptor F4) Sequence analysis of this gene suggests that it is encodes a member of the superfamily of G protein-couple receptors. G protein-coupled receptors typically contain seven hydrophobic transmembrane domains, interact with guanine nucleotide binding regulatory proteins, and detect molecules outside the cell and act to transduce these signals into intracellular responses. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2016]

Feb 17, 2024

The c.221T>C (p.I74T) alteration is located in exon 4 (coding exon 3) of the ADGRF4 gene. This alteration results from a T to C substitution at nucleotide position 221, causing the isoleucine (I) at amino acid position 74 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
