Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_006715.4(MAN2C1):​c.3053G>A​(p.Arg1018His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000118 in 1,613,978 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 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. R1018C) has been classified as Uncertain significance.

Genes affected
MAN2C1 (HGNC:6827): (mannosidase alpha class 2C member 1) Predicted to enable alpha-mannosidase activity. Predicted to be involved in oligosaccharide catabolic process. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
NEIL1 (HGNC:18448): (nei like DNA glycosylase 1) This gene is a member of the Nei endonuclease VIII-like gene family which encodes DNA glycosylases. The encoded enzyme participates in the DNA repair pathway by initiating base excision repair by removing damaged bases, primarily oxidized pyrimidines. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2012]
