Genes affected
ZBED4 (HGNC:20721): (zinc finger BED-type containing 4) Enables identical protein binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II. Located in cytoplasm and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
ALG12 (HGNC:19358): (ALG12 alpha-1,6-mannosyltransferase) This gene encodes a member of the glycosyltransferase 22 family. The encoded protein catalyzes the addition of the eighth mannose residue in an alpha-1,6 linkage onto the dolichol-PP-oligosaccharide precursor (dolichol-PP-Man(7)GlcNAc(2)) required for protein glycosylation. Mutations in this gene have been associated with congenital disorder of glycosylation type Ig (CDG-Ig)characterized by abnormal N-glycosylation. [provided by RefSeq, Jul 2008]

The c.206A>G (p.K69R) alteration is located in exon 2 (coding exon 1) of the ZBED4 gene. This alteration results from a A to G substitution at nucleotide position 206, causing the lysine (K) at amino acid position 69 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
