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]

The c.1532A>G (p.Y511C) alteration is located in exon 11 (coding exon 11) of the KY gene. This alteration results from a A to G substitution at nucleotide position 1532, causing the tyrosine (Y) at amino acid position 511 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
