chr1-225100772-T-A

Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 6P and 2B. PM2 PP3_Strong BP6_Moderate

The NM_001367479.1(DNAH14):c.3755T>A(p.Met1252Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 9/14 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★).

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 Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.944
• BP6: Variant 1-225100772-T-A is Benign according to our data. Variant chr1-225100772-T-A is described in ClinVar as [Benign]. Clinvar id is 190455.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr1-225100772-T-A is described in Lovd as [Benign].
