Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 4P and 8B. PVS1_Moderate PM2 BP6_Very_Strong

The NM_001369.3(DNAH5):​c.4356-3_4356-2del variant causes a splice acceptor, splice polypyrimidine tract, intron change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,842 control chromosomes in the GnomAD database, with no homozygous occurrence. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Likely benign (★★).

Genes affected

DNAH5 (HGNC:2950): (dynein axonemal heavy chain 5) This gene encodes a dynein protein, which is part of a microtubule-associated motor protein complex consisting of heavy, light, and intermediate chains. This protein is an axonemal heavy chain dynein. It functions as a force-generating protein with ATPase activity, whereby the release of ADP is thought to produce the force-producing power stroke. Mutations in this gene cause primary ciliary dyskinesia type 3, as well as Kartagener syndrome, which are both diseases due to ciliary defects. [provided by RefSeq, Oct 2009]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.017297298 fraction of the gene. Cryptic splice site detected, with MaxEntScore 9, offset of 0 (no position change), new splice context is: tcatgttggtgtcccttcAGatg. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 5-13864638-CTG-C is Benign according to our data. Variant chr5-13864638-CTG-C is described in ClinVar as [Likely_benign]. Clinvar id is 258033.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
