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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -20 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0030414462).
BP6
Variant 21-42476045-C-T is Benign according to our data. Variant chr21-42476045-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 241790.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00249 (379/151974) while in subpopulation AFR AF= 0.00808 (335/41468). AF 95% confidence interval is 0.00737. There are 3 homozygotes in gnomad4. There are 188 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 3 AR gene
