Genes affected
DKC1 (HGNC:2890): (dyskerin pseudouridine synthase 1) This gene functions in two distinct complexes. It plays an active role in telomerase stabilization and maintenance, as well as recognition of snoRNAs containing H/ACA sequences which provides stability during biogenesis and assembly into H/ACA small nucleolar RNA ribonucleoproteins (snoRNPs). This gene is highly conserved and widely expressed, and may play additional roles in nucleo-cytoplasmic shuttling, DNA damage response, and cell adhesion. Mutations have been associated with X-linked dyskeratosis congenita. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 10 ACMG points.
PM1
?
In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_001363.5
PM2
?
Very rare variant in population databases, with high coverage;
PP2
?
Missense variant where missense usually causes diseases, DKC1
PP3
?
MetaRNN computational evidence supports a deleterious effect, 0.95
PP5
?
