Variant 1-246849977-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_001323342.2(AHCTF1):c.6029C>T(p.Thr2010Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000274 in 1,461,634 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign 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. T2010A) has been classified as Uncertain significance.

The c.6056C>T (p.T2019I) alteration is located in exon 33 (coding exon 33) of the AHCTF1 gene. This alteration results from a C to T substitution at nucleotide position 6056, causing the threonine (T) at amino acid position 2019 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
