Variant chr17-15304141-T-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_031898.3(TEKT3):c.1268A>C(p.Glu423Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,828 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. E423K) has been classified as Uncertain significance.

Genes affected

TEKT3 (HGNC:14293): (tektin 3) This gene product belongs to the tektin family of proteins. Tektins comprise a family of filament-forming proteins that are coassembled with tubulins to form ciliary and flagellar microtubules. The exact function of this gene is not known.

Apr 27, 2022

The c.1268A>C (p.E423A) alteration is located in exon 9 (coding exon 7) of the TEKT3 gene. This alteration results from a A to C substitution at nucleotide position 1268, causing the glutamic acid (E) at amino acid position 423 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
