Forearm bone density in pedigreed baboons mapped to a region matching human chromosome 11q12-13, one strand of the research gathered here on BMD QTL 15.

Adult-onset weakness, sensory loss and gait changes mark CMT2P, which has been linked to LRSAM1, SBF1 and the m.9185T>C variant in the MT-ATP6 gene.

Roughly one in 4,000 newborns has this deletion, which can bring developmental delay, growth retardation, dysmorphic facial features and sleep problems.

Unified testing for polyposis and nonpolyposis syndromes raised diagnostic yield in a Swedish study, and work on the CRP variant rs1205 and rapamycin resistance goes on.

The first milk, colostrum carries antibodies and growth factors that support a newborn's immune system. Genetic testing can detect bacteria and antibiotic resistance.

Sight loss present from birth can come from several genes: testing distinguishes CSNB, Usher syndrome and Aland Island Eye Disease, including CACNA1F variants.

Premature red cell destruction brings fatigue, pallor, jaundice and spleen enlargement; exome sequencing can find ATP11C or COL4A1 mutations behind unexplained cases.
