  • Babbs C, Heller R, Everman D B, Crocker M, Twigg S R F, Schwartz C E, Giele H, Wilkie A O M.: A new locus for split hand/foot malformation with long bone deficiency (SHFLD) at 2q14.2 identified from a chromosome translocation. Hum. Genet. 122: 191-199; DOI=10.1007/s00439-007-0390-7, 2007. [PubMed: 17569090]
    46,XY,t(2;18)(q14.2;p11.2)dn
    This patient was 11 years old and studied in detail from the age of 6 years for SHFLD.
    The breakpoint on chromosome 2 was at 120,960,699bp and at 10,368,893bp on chromosome 18. The authors concluded that any of the nine genes (PTPN4, EPB41L5, FAM11B, RALB, 1NHBB, FLJ14816, GL12, TFCP2L1, CLASP1) may be potentially affected by a regulatory mutation within the novel SHFLD region.
    Aberration: Reciprocal translocation

    46,XY,t(2;4)(2pter->cen->q14.2::4q35->4qter;4pter->cen->4q35::2q14.2->2qter)de novo
    The 3 year old patient had severe growth and mental retardation, lobar holoprosencephaly, hypertelorism, microphthalmos, and iris, choroid, and retina colobomata.
    Aberration: Reciprocal translocation
    Index Terms: Holoprosencephaly, hypertelorism, and ectrodactyly syndrome (HHES).

    At the 20th week of pregnancy, an ultrasound examination showed slight hydramnios and continuously closed hands. The newborn showed mild dysmorphic features: poorly differentiated ears, short neck, widely spaced nipples, distal anterior hypospadias, and bilateral hydrocele. At 7 months, psychomotor developmental retardation was seen.
    Aberration: Complex translocation
    Negative band

    46,XX,der(2)der(7)t(2;7)(q14.2;q21.13)pat.
    Several members were carriers of the translocation but only two had SHFD (split hand/foot deformity).
    SHFD locus may be on 7q.
