Variant 1-108835055-A-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_152763.5(AKNAD1):c.1538T>C(p.Ile513Thr) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000704 in 1,421,428 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/23 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★).

Dec 14, 2023

The c.1538T>C (p.I513T) alteration is located in exon 8 (coding exon 7) of the AKNAD1 gene. This alteration results from a T to C substitution at nucleotide position 1538, causing the isoleucine (I) at amino acid position 513 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
