Variant 9-135626169-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_182974.3(GLT6D1):c.157G>A(p.Ala53Thr) variant causes a missense change. The variant allele was found at a frequency of 0.00000628 in 1,592,550 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. A53V) has been classified as Uncertain significance.

Genes affected

GLT6D1 (HGNC:23671): (glycosyltransferase 6 domain containing 1) The GT6 glycosyltransferases gene family, which includes the ABO blood group (ABO; MIM 110300) and GLT6D1, shows a complex evolution pattern, with multiple events of gain and loss in different mammal species. In humans, the ABO gene is considered the sole functional member, although the O allele is null and is fixed in certain populations (summary by Casals et al. (2009) [PubMed 19218399]).[supplied by OMIM, Jan 2011]

Ambry Genetics

May 25, 2022

The c.157G>A (p.A53T) alteration is located in exon 4 (coding exon 3) of the GLT6D1 gene. This alteration results from a G to A substitution at nucleotide position 157, causing the alanine (A) at amino acid position 53 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
