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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), HYDIN. . Gene score misZ 0.81019 (greater than the threshold 3.09). Trascript score misZ 4.6175 (greater than threshold 3.09). GenCC has associacion of gene with primary ciliary dyskinesia 5, primary ciliary dyskinesia.
BP4
Computational evidence support a benign effect (MetaRNN=0.30144846).

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.14932G>A (p.G4978R) alteration is located in exon 86 (coding exon 85) of the HYDIN gene. This alteration results from a G to A substitution at nucleotide position 14932, causing the glycine (G) at amino acid position 4978 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
