Variant summary

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

The NM_001123364.3(METTL24):ā€‹c.314G>Cā€‹(p.Arg105Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000587 in 1,193,428 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R105Q) has been classified as Uncertain significance.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.314G>C (p.R105P) alteration is located in exon 1 (coding exon 1) of the METTL24 gene. This alteration results from a G to C substitution at nucleotide position 314, causing the arginine (R) at amino acid position 105 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
