Genes affected

GCM1 (HGNC:4197): (glial cells missing transcription factor 1) This gene encodes a DNA-binding protein with a gcm-motif (glial cell missing motif). The encoded protein is a homolog of the Drosophila glial cells missing gene (gcm). This protein binds to the GCM-motif (A/G)CCCGCAT, a novel sequence among known targets of DNA-binding proteins. The N-terminal DNA-binding domain confers the unique DNA-binding activity of this protein. [provided by RefSeq, Jul 2008]

Apr 19, 2023

The c.1248G>T (p.M416I) alteration is located in exon 6 (coding exon 5) of the GCM1 gene. This alteration results from a G to T substitution at nucleotide position 1248, causing the methionine (M) at amino acid position 416 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
