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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BS1
Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.0000315 (46/1460836) while in subpopulation EAS AF= 0.000252 (10/39682). AF 95% confidence interval is 0.000136. There are 0 homozygotes in gnomad4_exome. There are 23 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The c.1778G>A (p.R593Q) alteration is located in exon 11 (coding exon 11) of the KY gene. This alteration results from a G to A substitution at nucleotide position 1778, causing the arginine (R) at amino acid position 593 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
