Seckel Syndrome 2‚ also known as MICROCEPHALIC PRIMORDIAL DWARFISM 2 or SECKEL-TYPE DWARFISM 2‚ is a rare autosomal recessive disorder characterized by growth retardation‚ microcephaly with mental retardation‚ and a unique facial appearance.
Genetic Basis of Seckel Syndrome 2
Seckel Syndrome 2 is linked to gene map locations⁚ Seckel syndrome 1 on chromosome 3 (3q22-q24)‚ Seckel syndrome 2 on chromosome 18 (18p11.31-q11)‚ and Seckel syndrome 3 on chromosome 14 (14q21-q22).
Chromosomal Locations and Specific Genes
Seckel Syndrome 2 has specific gene map locations‚ including Seckel syndrome 1 on chromosome 3 (3q22-q24)‚ Seckel syndrome 2 on chromosome 18 (18p11.31-q11)‚ and Seckel syndrome 3 on chromosome 14 (14q21-q22). Different genes‚ such as ATR‚ RBBP8‚ CENPJ‚ CEP152‚ CEP63‚ ATRIP‚ and NSMCE2‚ have been linked to different types of Seckel syndrome.
