Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_080860.4(RSPH1):c.650T>G(p.Leu217Trp) variant causes a missense change. The variant allele was found at a frequency of 0.00858 in 1,610,502 control chromosomes in the GnomAD database, including 76 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L217F) has been classified as Uncertain significance.

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 was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.009697765).

BP6

Variant 21-42477368-A-C is Benign according to our data. Variant chr21-42477368-A-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 241788.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00704 (1048/148776) while in subpopulation NFE AF = 0.0108 (718/66742). AF 95% confidence interval is 0.0101. There are 10 homozygotes in GnomAd4. There are 482 alleles in the male GnomAd4 subpopulation. Median coverage is 34. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 10 AR,AD gene
