    Nunes et al (1994) patient was 19 years old.

    Patient MH 810502.
    46,XX,del(7)(pter->q11.2::q22.1->qter).,Parental karyotypes were normal.
    Patient reported by Ignatius et al:
    46,XY,inv(1)(q21q23),t(4;7)(q31.1;q21.3),inv(11)(p15.1q23).
    The patient was 54 years old, deaf, IQ of 30 and institutionalised since age of 42. All of his four limbs were affected with split hand /split foot anomaly.
    Data on seven patients are presented, some reported earlier (Sharland et al , 1991 cited under 5q112; Roberts et al, 1991 cited under 7p151).
    Patient T1:46,XX,t(7;12)(q22.1;q24.2).&Patient D2:46,XY,del(7)(q21.12->q22.1).
    Patient T1 had bilateral split hand/split foot and mild speech delay; D2 had normal hands, bilateral split foot, MR, microcephaly, coloboma, and short stature.
    The order of DNA markers is PON-D7S812-SHFD1-D7S811-ASNS. SHFD1 is mapped in the 7q21.3-q22.1 region.
    Aberration: ID,ST,CT,IP,PI

    A 33-year old woman who was phenotypically normal had a history of multiple miscarriages.

    Manifestations include absence of lower limbs, unilateral ectrodactyly, facial anomalies, gingival hyperplasia, feeding problems, and atrial septal defect.
    It is suggested that there may be a locus in the vicinity of 7(q21 or 22) for limb differentiation.
    Aberration: Interstitial deletion
    Chromosomal Aneuploidy: 7q-

    46,XY.ish del(7)(DLX5-,DLX6-,q21.3).
    The four-year-old was referred because of split hand/split foot malformation. Further examination by magnetic resonance tomography showed a malformation of the inner ear typical for Mondini dysplasia.
    Deletion is approximately 0.9-1.8 Mb. The breakpoints are located between the DNCI1 gene and marker D7S821 at the proximal border and between the DLX5 gene and marker D7S618 at the distal border.
    Aberration: Interstitial deletion
    Chromosomal Aneuploidy: 7q-
    Index Terms: SHFM1,SHFM1D,Mondini dysplasia
