Genes affected

HYDIN (HGNC:19368): (HYDIN axonemal central pair apparatus protein) This gene encodes a protein that may be involved in cilia motility. Mutations in this gene cause of autosomal recessive primary ciliary dyskinesia-5, a disorder characterized by the accumulation of cerebrospinal fluid within the ventricles of the brain. A duplicate copy of this gene has been found in humans on chromosome 1. [provided by RefSeq, Jan 2013]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PP2: Missense variant where missense usually causes diseases, HYDIN
• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF. No scorers claiming Uncertain. No scorers claiming Benign.
• PP5: Variant 16-70988133-C-A is Pathogenic according to our data. Variant chr16-70988133-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 39698.Status of the report is no_assertion_criteria_provided, 0 stars.
