Genes affected

ALX3 (HGNC:449): (ALX homeobox 3) This gene encodes a nuclear protein with a homeobox DNA-binding domain that functions as a transcriptional regulator involved in cell-type differentiation and development. Preferential methylation of this gene's promoter is associated with advanced-stage neuroblastoma tumors. [provided by RefSeq, Jul 2008]

(HGNC:):

STRIP1 (HGNC:25916): (striatin interacting protein 1) This gene encodes a member of the striatin-interacting phosphatase and kinase complex, which is involved in localization of the Golgi body. The encoded protein participates in cytosketelal organization. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2012]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.972
• PP5: Variant 1-110061550-T-C is Pathogenic according to our data. Variant chr1-110061550-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 4643.Status of the report is no_assertion_criteria_provided, 0 stars.
