Genes affected

KY (HGNC:26576): (kyphoscoliosis peptidase) The protein encoded by this gene belongs to the transglutaminase-like superfamily. The protein is involved in the function, maturation and stabilization of the neuromuscular junction and may be required for normal muscle growth. Mutations in this gene are associated with myopathy, myofibrillar, 7. [provided by RefSeq, Apr 2017]

CEP63 (HGNC:25815): (centrosomal protein 63) This gene encodes a protein with six coiled-coil domains. The protein is localized to the centrosome, a non-membraneous organelle that functions as the major microtubule-organizing center in animal cells. Several alternatively spliced transcript variants have been found, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.07744372).

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0000788 (12/152250) while in subpopulation NFE AF= 0.000176 (12/68038). AF 95% confidence interval is 0.000102. There are 0 homozygotes in gnomad4. There are 3 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1895C>G (p.A632G) alteration is located in exon 11 (coding exon 11) of the KY gene. This alteration results from a C to G substitution at nucleotide position 1895, causing the alanine (A) at amino acid position 632 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
