Which presenting symptom might alert the PNP to the presence of a possible genetic disorder?

Which presenting symptom might alert the PNP to the presence of a possible genetic disorder?

• A. <10% on growth chart, Tanner I, and learning difficulties
• B. Precocious puberty, developmental delays, gifted piano player
• C. Lactose intolerance, frequent ear infections, speech delays
• D. Peanut allergy, right-sided weakness, and exhibits bullying behavior

Answer: (A)

Recognizing a possible genetic disorder often comes from seeing multisystem involvement in a child. When growth is markedly restricted (below the 10th percentile), puberty has not begun (Tanner stage I), and there are learning difficulties, these findings together suggest a syndromic condition that can affect growth, development, and cognitive function. This constellation points toward a genetic or chromosomal etiology and should prompt appropriate referrals for genetics evaluation, endocrine assessment, and early intervention services. Other options describe issues that are less consistent with a single genetic syndrome. Precocious puberty reflects early hormonal activation rather than delayed maturation; a mix of lactose intolerance, ear infections, and speech delays can occur in many children without implying a genetic disorder; and peanut allergy with focal neurologic signs and bullying behavior doesn’t form a coherent hereditary multisystem pattern. The combination of significant growth delay, delayed puberty, and learning difficulties best signals the possibility of a genetic disorder.
