Genes affected

DNAH14 (HGNC:2945): (dynein axonemal heavy chain 14) Dyneins are microtubule-associated motor protein complexes composed of several heavy, light, and intermediate chains. Two major classes of dyneins, axonemal and cytoplasmic, have been identified. DNAH14 is an axonemal dynein heavy chain (DHC) (Vaughan et al., 1996 [PubMed 8812413]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.46).
• BP6: Variant 1-225152718-C-G is Benign according to our data. Variant chr1-225152718-C-G is described in ClinVar as [Benign]. Clinvar id is 402651.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.289 with no splicing effect.
• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.00299 (4173/1397686) while in subpopulation MID AF= 0.0338 (192/5686). AF 95% confidence interval is 0.0299. There are 40 homozygotes in gnomad4_exome. There are 2351 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 5 AR gene
