Genes affected

TSPYL6 (HGNC:14521): (TSPY like 6) Predicted to enable chromatin binding activity and histone binding activity. Predicted to be involved in nucleosome assembly. Predicted to be active in chromatin and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACYP2 (HGNC:180): (acylphosphatase 2) Acylphosphatase can hydrolyze the phosphoenzyme intermediate of different membrane pumps, particularly the Ca2+/Mg2+-ATPase from sarcoplasmic reticulum of skeletal muscle. Two isoenzymes have been isolated, called muscle acylphosphatase and erythrocyte acylphosphatase on the basis of their tissue localization. This gene encodes the muscle-type isoform (MT). An increase of the MT isoform is associated with muscle differentiation. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2016]

LOC105374610 (HGNC:):
