Genes affected

CWF19L1 (HGNC:25613): (CWF19 like cell cycle control factor 1) This gene encodes a member of the CWF19 protein family. Mutations in this gene have been associated with autosomal recessive spinocerebellar ataxia-17 and mild cognitive disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

SNORA12 (HGNC:32600): (small nucleolar RNA, H/ACA box 12) Small nucleolar RNAs (snoRNAs) are small noncoding RNAs involved in RNA processing. Box H/ACA snoRNAs, such as SNORA12, direct the conversion of uridine to pseudouridine at specific residues of ribosomal RNAs or small nuclear RNAs (snRNAs) (Gu et al., 2005).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
