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 Benign. Variant got -12 ACMG points.

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=0.0020711422).
BP6
Variant 16-70807800-A-G is Benign according to our data. Variant chr16-70807800-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 3037169.Status of the report is no_assertion_criteria_provided, 0 stars.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0042 (640/152314) while in subpopulation AFR AF= 0.0148 (615/41568). AF 95% confidence interval is 0.0138. There are 1 homozygotes in gnomad4. There are 305 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 3 AR gene
