Genes affected

SYNE4 (HGNC:26703): (spectrin repeat containing nuclear envelope family member 4) This gene is a member of the nesprin family of genes, that encode KASH (Klarsicht, Anc-1, Syne Homology) domain-containing proteins. In addition to the KASH domain, this protein also contains a coiled-coil and leucine zipper region, a spectrin repeat, and a kinesin-1 binding region. This protein localizes to the outer nuclear membrane, and is part of the linker of nucleoskeleton and cytoskeleton (LINC) complex in the nuclear envelope. LINC complexes are formed by SUN (Sad1, UNC-84)-KASH pairs, and are thought to mechanically couple nuclear components to the cytoskeleton. Mutations in this gene have been associated with progressive high-frequency hearing loss. The absence of this protein in mice also caused hearing loss, and changes in hair cell morphology in the ears. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2015]

ENSG00000248101 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.77).
• BP6: Variant 19-36008544-C-T is Benign according to our data. Variant chr19-36008544-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 504815.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr19-36008544-C-T is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.000382 (558/1461106) while in subpopulation MID AF= 0.00625 (33/5280). AF 95% confidence interval is 0.00457. There are 2 homozygotes in gnomad4_exome. There are 261 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAdExome4 at 2 AR gene
