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. -
