16-71537123-G-A

Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_StrongBP6_Moderate

The NM_001166395.2(CHST4):​c.446G>A​(p.Arg149Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000108 in 1,613,968 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R149W) has been classified as Uncertain significance.

Genes affected
CHST4 (HGNC:1972): (carbohydrate sulfotransferase 4) This gene encodes an N-acetylglucosamine 6-O sulfotransferase. The encoded enzyme transfers sulfate from 3'phosphoadenosine 5'phospho-sulfate to the 6-hydroxyl group of N-acetylglucosamine on glycoproteins. This protein is localized to the Golgi and is involved in the modification of glycan structures on ligands of the lymphocyte homing receptor L-selectin. Alternate splicing in the 5' UTR results in multiple transcript variants that encode the same protein. [provided by RefSeq, Oct 2009]
ZNF19 (HGNC:12981): (zinc finger protein 19) The protein encoded by this gene contains a zinc finger, a nucleic acid-binding domain present in many transcription factors. This gene is located in a region next to ZNF23, a gene also encoding a zinc finger protein, on chromosome 16. [provided by RefSeq, Jul 2008]
