Genes affected

FAM107A (HGNC:30827): (family with sequence similarity 107 member A) Predicted to enable actin binding activity. Involved in several processes, including negative regulation of G1/S transition of mitotic cell cycle; negative regulation of focal adhesion assembly; and regulation of cytoskeleton organization. Located in several cellular components, including focal adhesion; ruffle membrane; and stress fiber. [provided by Alliance of Genome Resources, Apr 2022]

LOC107984079 (HGNC:):

The c.67G>C (p.E23Q) alteration is located in exon 3 (coding exon 1) of the FAM107A gene. This alteration results from a G to C substitution at nucleotide position 67, causing the glutamic acid (E) at amino acid position 23 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
