2 MEMORANDUM OPINION

3 VARGAS, Judge.

4 {1} This is an appeal from the district court’s decision to exclude the opinion

5 testimony of Plaintiff Heather Stowell’s only expert witness, a pharmacologist, as to

6 the cause of her minor child’s neurodegenerative disorder. Plaintiff also appeals the

7 district court’s entry of summary judgment in favor of Defendant Tushar Dandade,

8 M.D., following the exclusion of Plaintiff’s expert. As discussed below, we conclude

9 that the district court did not err by excluding the testimony of Plaintiff’s expert

10 pharmacologist; and, absent other expert medical testimony on causation, the district

11 court’s entry of summary judgment for Defendant was proper.

12 BACKGROUND

13 {2} After becoming pregnant with her first child in 2008, Plaintiff sought prenatal

14 treatment from Defendant. During the course of her pregnancy, Defendant prescribed

15 Zoloft to Plaintiff. Zoloft is a selective serotonin reuptake inhibitor (SSRI) used to

16 treat disorders such as depression and anxiety.

17 {3} Plaintiff gave birth to a baby girl, (R.R.) in April 2009. At birth, R.R. appeared

18 to be a normal, healthy child with no apparent medical problems. Around age one,

19 however, R.R. began displaying symptoms of neurodegeneration, which have steadily

2 1 continued. Genetic and metabolic testing have failed to identify a cause for R.R.’s

2 condition.

3 {4} Plaintiff filed suit against Defendant, claiming that the Zoloft he prescribed and

4 she took during her pregnancy was the cause of R.R.’s neurodegenerative disorder.

5 In support of her claim, Plaintiff named Dr. Patrick Ronaldson, Ph.D., as her only

6 expert witness to testify about the medical causation of R.R.’s condition and damages.

7 {5} Dr. Ronaldson holds a Ph.D. in pharmacology, but is not a medical doctor and

8 is not licensed to diagnose medical conditions. As part of his testimony, Dr.

9 Ronaldson explained that he did not intend to offer opinions on the medical diagnosis

10 of R.R. Instead, his testimony was limited to the etiology of R.R.’s neurodegenerative

11 condition, specifically, the biological mechanisms that could have caused the

12 symptoms that are apparent in R.R.

13 {6} In support of his theory that Zoloft was the cause of R.R.’s neurodegenerative

14 disorder, Dr. Ronaldson explained, “[T]here is evidence in the scientific literature that

15 hypoxia, including fetal hypoxia, can be caused by in utero exposure to SSRIs

16 including [Zoloft].” According to Dr. Ronaldson, hypoxia can cause neurological

17 damage; periventricular leukomalacia (PVL) is an established biomarker of hypoxia;

18 and there are three references in R.R.’s very substantial medical records to PVL.

19 These three references, along with Dr. Ronaldson’s understanding that board-certified

3 1 geneticists who had examined R.R. had ruled out a genetic cause for R.R.’s condition,

2 form the basis of Dr. Ronaldson’s opinion. In arriving at his conclusion, Dr.

3 Ronaldson did not review R.R.’s testing images or actual lab results. Instead, he

4 reviewed reports from the geneticists and radiologists who treated R.R.

5 {7} Dr. Ronaldson conceded that none of the studies on which he relied to reach his

6 opinion demonstrate that Zoloft can cause a neurodegenerative disorder with the

7 symptoms of those exhibited by R.R. He further admitted that no study to date

8 supports his exact hypothesis.

9 {8} In support of his motion to exclude Dr. Ronaldson’s testimony, Defendant

10 presented evidence from R.R.’s treating pediatric geneticist and from his own expert

11 geneticist and teratologist that a genetic explanation for R.R.’s neurodegenerative

12 condition had not been ruled out and was the likely cause of R.R.’s condition. Dr.

13 Randall Heidenreich, Chief of the Division of Pediatric Genetics at the University of

14 New Mexico, evaluated R.R. in an attempt to identify a genetic cause for her

15 condition. He was unable to identify a specific genetic basis for her

16 neurodegeneration; however, Dr. Heidenreich continues to strongly believe that R.R.

17 suffers from a genetic alteration that might be identified using exome or genome

18 sequencing that has not yet been performed on R.R.

4 1 {9} Dr. Margaret Adam, M.D., a clinical geneticist and teratologist who testified on

2 behalf of Defendant, agreed with the assessment of Dr. Heidenreich. Dr. Adam

3 testified that, in her opinion, to a reasonable degree of medical probability, the cause

4 of R.R.’s neurodegenerative condition was genetic. According to Dr. Adam, that R.R.

5 was normal at birth but began exhibiting degenerative features around one year of age,

6 that the degenerative features continued to progress, and that R.R.’s whole brain was

7 affected all support her and Dr. Heidenreich’s conclusions that the cause of R.R.’s

8 condition is genetic. Dr. Adam confirmed Dr. Ronaldson’s testimony that there were

9 no studies in the field of genetics, teratology, or pediatrics that support the conclusion

10 that prenatal exposure to Zoloft can cause a neurodegenerative condition such as

11 R.R.’s. Further, Dr. Adam testified that the well-described effects of Zoloft on a fetus

12 in utero are typically in the form of autonomic dysfunction and respiratory issues,

13 none of which were present in R.R.

14 {10} Finally, Defendant submitted evidence from at least three separate sources,

15 concluding that R.R. did not suffer from hypoxia or PVL, the conditions relied upon

16 by Dr. Ronaldson to reach his conclusion. Dr. Adam testified that nowhere in R.R.’s

17 medical records had any physician made a diagnosis of PVL in R.R. Another of

18 Defendant’s expert witnesses, Gail McCarver, M.D., a board certified pediatrician,

19 neonatologist, and clinical pharmacologist, submitted an affidavit refuting Dr.

5 1 Ronaldson’s assumption that hypoxia is the medical cause of R.R.’s condition, instead

2 concluding that R.R.’s “clinical presentation does not correlate with chronic hypoxia

3 in utero.” Finally, Dr. Marvin Nelson, M.D., a pediatric neuroradiologist submitted

4 his affidavit, concluding “that the head imaging findings [for R.R.] do not suggest

5 hypoxia during the perinatal period and this is not HIE (hypoxic-ischemic

6 encephalopathy) or PVL (periventricular leukomalacia).”
