Genetic Variant NM_004479.4:c.713C>A (chr9-137031026-G-T) – ACMG Classification: Likely_pathogenic (6 pts)

Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_004479.4(FUT7):c.713C>A(p.Thr238Lys) variant causes a missense change. The variant allele was found at a frequency of 0.000000685 in 1,460,506 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T238M) has been classified as Uncertain significance.

Genes affected

FUT7 (HGNC:4018): (fucosyltransferase 7) The protein encoded by this gene is a Golgi stack membrane protein that is involved in the creation of sialyl-Lewis X antigens. The encoded protein can direct the synthesis of the E-selectin-binding sialyl-Lewis X moiety. [provided by RefSeq, Jul 2008]
