Table 3 Previously suggested pedigree symbols for TGD patients.
Transgender man (assigned female at birth) | Transgender woman (assigned male at birth) | Non-binary or other gender-diverse identities (assigned female at birth) | Non-binary or other gender-diverse identities (assigned male at birth) | |
|---|---|---|---|---|
Bennett et al. [8] |

|
|
Comments | Recommend symbol representing “phenotypic gender”, which is ambiguous Assuming sex chromosomes may be inaccurate and cause clinician discomfort [9, 10] | |||
Provenzale et al. [11] |
|
| ||
Comments | Denoting sex assigned at birth in the centre could be interpreted as considering that this is core to the patient’s identity Symbols could easily be misdrawn/misinterpreted | |||
Barnes et al. [7] |
|
|
|
|
Comments | Use symbol that aligns to patient’s gender Annotation to indicate sex assigned at birth is preferable to sex chromosomes Participants indicated that diamond shape did not seem validating, as it is frequently used when gender is not known Recommendations supported by Bennett et al. [12] | |||
Tuite et al. [13] |
|
|
|
|
Comments | “Superscript symbols” eliminate the need for annotation Deviation from standardised pedigree and astrological symbols may cause confusion Triangle could be confused for “pregnancy not carried to term” | |||
von Vaupel-Klein & Walsh [1] |
|
|
|
|
Comments | Incorporate Barnes et al. [7] recommendations and suggest alternative for non-binary individuals with less potential for confusion and feeling of gender identity being invalidated | |||
