STATUS ACRONYMS FREE (F): animal tested free of defect (ex. DDF)
R# 10569960 NEUROPATHIC HYDROCEPHALUS (NH): is a lethal disorder linked to a genetic condition caused by a recessive mutation that affects Angus and Angus-influenced cattle. Affected calves are born dead with an extremely large crani- um with little to no brain material or spinal cord. It is probable a large percentage of mortalities relating to NH occur through embryonic or fetal loss during gestation causing the defect to go unnoticed. AKA Water Head Syndrome. OSTEOPETROSIS (OS): is a lethal condition caused by a recessive mutation in Angus and Angus-influenced cattle and exhibits a recessive inheritance pattern. Affected calves are typically stillborn prematurely and they often have a small body size, flat skull, impacted molars, shortened lower jaw, protruding tongue, and leg bones that are easily broken. AKA Marble Bone. CED BW WW YW M TM CEM SC REA IMF FT OCULOCUTANEOUS HYPOPIGMENTATION (OH): is a non-lethal genetic condition with the genome of Angus and Angus-influenced cattle and exhibits a simple recessive inheritance pattern. Affected calves have eyes with irises that are pale blue around the pupil with a ten periphery and hair coats can have a slightly bleached color. While some affected calves can have sensitivity to light, they are believed to be otherwise normal functionally and physiologically. All EPDs, EPD accuracies, and EPD percentile ranks on sires reflect the January 2025 EPD update. EPD percentile ranks are compared to contemporaries within active sire listing: Black Brangus and Ultrablack sires are compared against the pooled population of active Black Brangus sires. Red Brangus and Ultrared sires are compared against the pooled population of active Red Brangus sires.

DDA) GENETIC DEFECTS CONTRACTURAL ARACHNODACTYLY (CA): a lethal disorder linked to a genetic condition caused by a recessive mutation that affects Angus and Angus-influenced cattle. While CA-affected calves are born alive, and most can walk, suckle and survive, their upper limb joints (particularly hip, stifle, and hock) have a reduced range of motion. Affect- ed calves appear normal by four to six months of age, but most perform poorly and are relatively tall and slender, with compromised feet and leg conformation. AKA Fawn Calf Syndrome. DEVELOPMENTAL DUPLICATION (DD): is a genetically transmitted simple recessive gene. When the gene associat- ed with DD is paired (two copies of the same allele) in mating, the results range from a high probability of early em- bryonic death or a severe case of calves born with extra limbs. Those animals identified as carriers (only one recessive allele) show no visible signs of the genetic condition and lead a normal life. ARTHROGRYPOSIS MULTIPLEX (AM): is a lethal condition caused by a DNA deletion event within the genome of Angus and Angus-influenced cattle and exhibits a recessive inheritance pattern. Affected calves are known to be still- born with a twisted spine and extended or contracted limbs. AKA Curly Calf Syndrome.
