In ISCN 2024: An International System for Human Cytogenomic Nomenclature [Cytogenet Genome Res. 2024;164(suppl 1), DOI: 10.1159/000538512 and 10.1159/isbn.978–3–318–07331–7] by Hastings RJ, Moore S, Chia N (editors), the following corrections to the ISCN should be noted.

In Chapter 6, Section 6.3.5 Composite Karyotype, Rule f, the line i

i. 45,XX,−15,del(17)(p11.3)

46,XX,+7,−15,del(17)(p11.3)

46,XX,+12,−15

47,XX,+7

47,XX,+15,del(17)(p11.3)

48,XX,+12,+15

The composite karyotype of these six metaphases is:

45∼48,XX,+7,+12,+15,−15,del(17)(p11.3)[cp6]

or

45∼48,XX,+7[2],+12[2],+15[2],−15[3],del(17)(p11.3)[3][cp6]

Should correctly read:

i. 45,XX,−15,del(17)(p11.2)

46,XX,+7,−15,del(17)(p11.2)

46,XX,+12,−15

47,XX,+7

47,XX,+15,del(17)(p11.2)

48,XX,+12,+15

The composite karyotype of these six metaphases is:

45∼48,XX,+7,+12,+15,−15,del(17)(p11.2)[cp6]

or

45∼48,XX,+7[2],+12[2],+15[2],−15[3],del(17)(p11.2)[3][cp6]

In Chapter 7, Section 7.2.1 Principles and Rules, Rule b, the line

47,XX,+12[20].ish del(17)(p13p13)(TP53)×1[17]/del(17)(TP53)×0[12]/17p13(TP53)×2[13]

Should correctly read:

47,XX,+12[20].ish

del(17)(p13p13)(TP53−)[17]/del(17)(p13p13)(TP53−),del(17)(p13p13)(TP53−)[12]/17p13(TP53)×2[13]

In Chapter 7, Section 7.2.6.2 Abnormal Signal Pattern, the line

i. ish t(13;20)(q34;p13)(163C9–,dj1061L1+;dj1061L1–,163C9+)

Should correctly read:

i. ish t(13;20)(q34;p13)(163C9–,dj1061L1+;163C9+,dj1061L1–)

In Chapter 7, Section 7.3.4.2.2 Abnormal Signal Pattern, the line

xii. 46,XY[20].ish 13q14(DLEU×2)[10],13q34(LAMP1×2)[10],14q32(IGH×2)[6],16q23(MAF×2)[6].nuc ish (DLEU×1,LAMP1×2)[17/200],(IGH,MAF)×3(IGH con MAF)×2[15/200]

Should correctly read:

xii.46,XY[20].ish 13q14(DLEU)×2[10],13q34(LAMP1)×2[10],14q32(IGH)×2[6],16q23(MAF)×2[6].nuc ish (DLEU×1,LAMP1×2)[17/200],(IGH,MAF)×3(IGH con MAF)×2[15/200]

In Chapter 7, Section 7.3.4.4.3 Two or More Chromosomes Normal Signal Pattern, the line

i. nuc ish (ASS1×2,ABL1×3,BCR×3)(ASS1/ABL1 con BCR)×1(ABL1 con BCR)×1[90/100]

Should correctly read:

i. nuc ish (ASS1,ABL1,BCR)×2[100]

In Chapter 7, Section 7.3.4.4.4 Two or More Chromosomes Abnormal Signal Pattern, the line

i. nuc ish (ASS1×2,ABL1×3,BCR×3)(ASS1/ABL1 con BCR)×1[90/100]

Should correctly read:

i. nuc ish (ASS1×2,ABL1×3,BCR×3)(ASS1/ABL1 con BCR)×1(ABL1 con BCR)×1[90/100]
