Genes affected
MYL6B (HGNC:29823): (myosin light chain 6B) Myosin is a hexameric ATPase cellular motor protein. It is composed of two heavy chains, two nonphosphorylatable alkali light chains, and two phosphorylatable regulatory light chains. This gene encodes a myosin alkali light chain expressed in both slow-twitch skeletal muscle and in nonmuscle tissue. Alternative splicing results in multiple transcript variants.

MYL6B-AS1 (HGNC:55472): (MYL6B antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 22, 2021The c.533C>G (p.T178S) alteration is located in exon 6 (coding exon 5) of the MYL6B gene. This alteration results from a C to G substitution at nucleotide position 533, causing the threonine (T) at amino acid position 178 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
