Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BP4_StrongBS2

The NM_031212.4(SLC25A28):c.121G>A(p.Ala41Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000488 in 1,394,038 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign 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. A41G) has been classified as Uncertain significance.

The c.121G>A (p.A41T) alteration is located in exon 1 (coding exon 1) of the SLC25A28 gene. This alteration results from a G to A substitution at nucleotide position 121, causing the alanine (A) at amino acid position 41 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
