[HTML][HTML] Absence of Maternal Methylation in Biparental Hydatidiform Moles from Women with NLRP7 Maternal-Effect Mutations Reveals Widespread Placenta …

M Sanchez-Delgado, A Martin-Trujillo, C Tayama… - PLoS …, 2015 - journals.plos.org
Familial recurrent hydatidiform mole (RHM) is a maternal-effect autosomal recessive

[HTML][HTML] Identification of rare de novo epigenetic variations in congenital disorders

M Barbosa, RS Joshi, P Garg, A Martin-Trujillo… - Nature …, 2018 - nature.com
Certain human traits such as neurodevelopmental disorders (NDs) and congenital
anomalies (CAs) are believed to be primarily genetic in origin. However, even after whole-genome …

[PDF][PDF] A survey of rare epigenetic variation in 23,116 human genomes identifies disease-relevant epivariations and CGG expansions

…, OL Rodriguez, N Patel, A Martin-Trujillo… - The American Journal of …, 2020 - cell.com
There is growing recognition that epivariations, most often recognized as promoter hypermethylation
events that lead to gene silencing, are associated with a number of human diseases…

[HTML][HTML] Human oocyte-derived methylation differences persist in the placenta revealing widespread transient imprinting

…, A Monteagudo-Sánchez, A Martin-Trujillo… - PLoS …, 2016 - journals.plos.org
Thousands of regions in gametes have opposing methylation profiles that are largely resolved

Altered expression of the imprinted transcription factor PLAGL1 deregulates a network of genes in the human IUGR placenta

I Iglesias-Platas, A Martin-Trujillo… - Human molecular …, 2014 - academic.oup.com
Genomic imprinting is the epigenetic process that results in monoallelic expression of
genes depending on parental origin. These genes are known to be critical for placental …

P Garg, A Martin-Trujillo, OL Rodriguez, SJ Gies… - The American Journal of …, 2021 - cell.com
Variable number tandem repeats (VNTRs) are composed of large tandemly repeated motifs,
many of which are highly polymorphic in copy number. However, because of their large size …

Genome‐wide allelic methylation analysis reveals disease‐specific susceptibility to multiple methylation defects in imprinting syndromes

F Court, A MartinTrujillo, V Romanelli, I Garin… - Human …, 2013 - Wiley Online Library
Genomic imprinting is the parent‐of‐origin‐specific allelic transcriptional silencing observed
in mammals, which is governed by DNA methylation established in the gametes and …

Genome-wide evaluation of the effect of short tandem repeat variation on local DNA methylation

A Martin-Trujillo, P Garg, N Patel, B Jadhav… - Genome …, 2023 - genome.cshlp.org
