Genes affected

ZMYND10 (HGNC:19412): (zinc finger MYND-type containing 10) This gene encodes a protein containing a MYND-type zinc finger domain that likely functions in assembly of the dynein motor. Mutations in this gene can cause primary ciliary dyskinesia. This gene is also considered a tumor suppressor gene and is often mutated, deleted, or hypermethylated and silenced in cancer cells. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015]

ZMYND10-AS1 (HGNC:40890): (ZMYND10 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -16 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BP6: Variant 3-50342008-T-A is Benign according to our data. Variant chr3-50342008-T-A is described in ClinVar as [Likely_benign]. Clinvar id is 525561.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000169 (247/1461868) while in subpopulation MID AF = 0.00312 (18/5768). AF 95% confidence interval is 0.00202. There are 1 homozygotes in GnomAdExome4. There are 127 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
