ORPHA:141261Morphological anomaly
What it is
A rare oblique facial cleft characterized by a congenital unilateral or bilateral defect beginning in the upper lip medial to the oral commissure and extending across the cheek as a groove ending between the middle and lateral third of the lower eyelid (resulting in coloboma). Bone involvement includes an alveolar cleft in the premolar region, extending across the maxilla lateral to the infraorbital nerve and up to the infraorbital rim and orbital floor. The malformation may be associated with Tessier number 3 and number 4 clefts, macrostomia, or anophthalmos.

Orphanet records these for the broader condition rather than for this specific form. They are a starting point, not a figure for this subtype — subtypes often differ, and some are defined by being rarer than the condition they sit under.
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
