Genes affected
RSPH4A (HGNC:21558): (radial spoke head component 4A) This gene encodes a protein that appears to be a component the radial spoke head, as determined by homology to similar proteins in the biflagellate alga Chlamydomonas reinhardtii and other ciliates. Radial spokes, which are regularly spaced along cilia, sperm, and flagella axonemes, consist of a thin 'stalk' and a bulbous 'head' that form a signal transduction scaffold between the central pair of microtubules and dynein. Mutations in this gene cause primary ciliary dyskinesia 1, a disease arising from dysmotility of motile cilia and sperm. Alternative splicing results in multiple transcript variants.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.77).
BP6
Variant 6-116616611-T-A is Benign according to our data. Variant chr6-116616611-T-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 1707228.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Likely_benign=1}.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00438 (666/152192) while in subpopulation AFR AF = 0.0151 (626/41532). AF 95% confidence interval is 0.0141. There are 4 homozygotes in GnomAd4. There are 311 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 4 AR,AD gene
