Genes affected

RSPH1 (HGNC:12371): (radial spoke head component 1) This gene encodes a male meiotic metaphase chromosome-associated acidic protein. This gene is expressed in tissues with motile cilia or flagella, including the trachea, lungs, airway brushings, and testes. Mutations in this gene result in primary ciliary dyskinesia-24. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2014]

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.59).

BP6

Variant 21-42493014-G-A is Benign according to our data. Variant chr21-42493014-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 241781.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-1.23 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00937 (1427/152258) while in subpopulation AFR AF = 0.0324 (1346/41524). AF 95% confidence interval is 0.031. There are 30 homozygotes in GnomAd4. There are 690 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 30 AR,AD gene
