Variant 4-155357499-A-C details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_001039580.2(MAP9):c.1071T>G(p.Asn357Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000521 in 1,536,854 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. N357H) has been classified as Uncertain significance.

The c.1071T>G (p.N357K) alteration is located in exon 8 (coding exon 7) of the MAP9 gene. This alteration results from a T to G substitution at nucleotide position 1071, causing the asparagine (N) at amino acid position 357 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
