Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_138797.4(ANKRD54):c.400G>A(p.Ala134Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000248 in 1,610,974 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. A134V) has been classified as Likely benign.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.400G>A (p.A134T) alteration is located in exon 3 (coding exon 3) of the ANKRD54 gene. This alteration results from a G to A substitution at nucleotide position 400, causing the alanine (A) at amino acid position 134 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
