Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_014838.3(ZBED4):c.175G>A(p.Ala59Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000206 in 1,459,118 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict 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. A59V) has been classified as Uncertain significance.

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]

ZBED4 links:

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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.175G>A (p.A59T) alteration is located in exon 2 (coding exon 1) of the ZBED4 gene. This alteration results from a G to A substitution at nucleotide position 175, causing the alanine (A) at amino acid position 59 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
